Directions for question nos. 1-2: Eighty Five children went to amusement park where they could ride on merry -go-round roller coaster and Ferris wheel .It was known that 20 of them have took all three rides and 55 of them have taken at least two of the three rides. Each ride cost Rs.1 and the total receipt of the amusement park was Rs.145.

1) How many children did not try any of the rides. ?
A) 5 B) 10 C) 15 D) 20

Ans. 15.

20 kids * 3 rides = Rs. 60
(55-20=)35 kids * 2 rides = Rs. 70
60 + 70 = Rs. 130
So, Rs. (145 – 130 = ) 15 are left for the other (85 – 55 = ) 30 kids . so only 15 of them can take a ride and rest 15 will be left out.

145 rides were taken. 20 of them took all three, i.e. Rs. 60 were spent, so 145-60= Rs. 85 are left for the others. Total kids were 85, so rest were 65. out of these 65,

2) How many children took exactly one ride?
A) 5 B) 10 C) 15 D) 20

Ans. 15

3) Four cities are connected by a road network as shown in the figure. In how many ways can you start from any city and come back to it without travelling on the same road more than once ?

B) 12
C) 16
D) 20

Ans. 12.

Consider the top city, the following are the 3 routes possible, starting from the leftmost edge. Since there are 3 edges emanating from each city and the figure is perfectly symmetrical, these 3 routes are possible from each edge, hence for any given city, the total number of routes = 4 * 3 = 12.

6.
class professor {};
class teacher : public virtual professor {};
class researcher : public virtual professor {};
class myprofessor : public teacher, public researcher {};

Referring to the sample code above, if an object of class “myprofessor” were created, how many instances of professor will it contain?
a) 0
b) 1
c) 2
d) 3
e) 4

Ans. b , here professor will be called a virtual base class since teacher and researcher derive from it virtually. This is used in multiple inheritance as shown here. If professor was not inherited virtually then there would be 2 instances of professor in the object of myprofessor.

7.
string somestring ;
Which of the following choices will convert a standard C++ string object “somestring” to a C string?
a) Copy.somestring () ;
b) somestring.c_str ()
c) &somestring [1]
d) std::cstring (somestring)
e) (char *) somestring

Ans. b

8.
class ba***
{
int x;
public:
void setx(int y) {x=y;}
};
class derived : ba*** {};
What is the access level for the member function “setx” in the class “derived” above?
a) private
b) local
c) global
d) public
e) protected

Ans. a

E) Table of Member Access Privileges
Access in Base Class Base Class Inherited as Access in Derived Class
Public Protected Private Public Public Protected No access1
Public Protected Private Protected Protected Protected No access1
Public Protected Private Private Private Private No access1
1 Unless friend declarations within the base class explicitly grant access.
So, the highest member accessibility is defined by the way a class is inherited, if it is inherited privately, then the highest member accessibility will be private. Default inheritance is private.

9.
class Alpha {
public:
char data[10000];
Alpha();
~Alpha();
};
class Beta {
public:
Beta() { n = 0; }
void FillData(Alpha a);

private:
int n;
};
How do you make the above sample code more efficient?
a) If possible, make the constructor for Beta private to reduce the overhead of public constructors.
b) Change the return type in FillData to int to negate the implicit return conversion from “int” to “void”.
c) Make the destructor for Alpha virtual.
d) Make the constructor for Alpha virtual.
e) Pass a const reference to Alpha in FillData

Ans. e. since u r passing a reference hence a new array will not be created in memory, whereas if u pass by value, then an array of 10000 chars will be created. Passing by reference only creates an alias for the original parameter (i.e., it points to the original parameter) and is same as passing by address, the only difference is that it can be used like an object instead of as a pointer, i.e., if param is &a, then u will write a.member, whereas if param is *a then u will write a->member.

10.
class Foo {
int x;
public:
Foo(int I);
};
If a class does not have a copy constructor explicitly defined one will be implicitly defined for it. Referring to the sample code above, which one of the following declarations is the implicitly created copy constructor?
a) Foo(Foo *f);
b) Foo(Foo &f);
c) Foo(const Foo *f);
d) Foo(const Foo &f);
e) Foo(int);

Ans. d. copy constructor takes an arg of its own type which is passed by ref and which should not be changed hence it is const

11.
class HasStatic {
static int I;
};
Referring to the sample code above, what is the appropriate method of defining the member variable “I”, and assigning it the value 10, outside of the class declaration?
a) HasStatic I = 10;
b) int static I = 10;
c) static I(10);
d) static I = 10;
e) int HasStatic::I = 10;

Ans. e

12.
class X
{
private:
int a;
protected:
X(){cout<<”X constructor was called”< ~X(){cout<<”X destructor was called”<};
Referring to the code above, which one of the following statements regarding “X” is TRUE?
a) X is an abstract class.
b) Only subclasses of X may create X objects.
c) Instances of X cannot be created.
d) X objects can only be created using the default copy constructor.
e) Only friends can create instances of X objects.

Ans. b. instances of X can be created only inside its subclasses.

13.
class Foo {
const int x;
protected:
Foo(int f);
~Foo();
};
Foo f;
Referring to the sample code above, why will the class declaration not compile?
a) The variable x is const.
b) The destructor is protected.
c) The destructor is not public.
d) The constructor is protected.
e) There is no default constructor.

Ans. e. if u don’t specify a constructor for a class, then the compiler generates the default constructor for u, but if u specify a constructor apart from the default constructor, then u must give the default constructor also, but only if u r creating an object which uses the default constructor. i.e., the following code is perfectly fine
class Foo {
public:
Foo(int f){}
~Foo(){}
};
Foo f(0);

But if u try to create an object of Foo like this
Foo f;
then this will give compiler error because there is no default constructor available.

14.
class Foo {
public:
Foo(int i) { }
};
class Bar : virtual Foo {
public:
Bar() { }
};

Bar b;

Referring to the above code, when the object ‘b’ is defined, a compiler error will occur. What action fixes the compiler error?
a) Adding a virtual destructor to the class Bar
b) Adding a constructor to Bar which takes an int parameter
c) Adding “Foo()” to the Bar constructor
d) Adding a copy constructor to the class Foo
e) Adding “Foo(0)” to the Bar::Bar initializer list

Ans. e

15. Which one of the following describes characteristics of “protected” inheritance?
a) The base class has access only to the public or protected members of the derived class.
b) The derived class has non-public, inheritable, access to all but the private members of the base class.
c) The derived class has access to all members of the base class.
d) The private members of the base class are visible within the derived class.
e) Public members of the derived class are privately accessible from the base class.

Ans. b

16. The “virtual” specifier in a member function enables which one of the following?
a) Monmorphism
b) Late binding
c) Metamorphism
d) Solomorphism
e) Inheritance

Ans. b. consider a base class B having a virtual function Foo, and a class D derived from this class also having a function Foo. Then when u create an object of a derived class, say dobj, and a ptr to base class, say pb, and point pb to dobj by saying pb = &dobj, and then call pb->Foo then the correct version of Foo will be called, i.e., the version in D will be called becz the object is of type D. this is called late binding, i.e., deferring the decision of calling which version of Foo until runtime since at compile time the type of object to which pb points may not be known.
class B {public: virtual void Foo(){cout<<”base”;}};
class D : public B {public: virtual void Foo(){cout<<”derv”;}};
D dobj;
B *pb;
pb = &dobj;
pb->Foo();

the output will be ‘derv’.
If Foo was not declared virtual in base class B , then the output would have been ‘base’.

17.
class X
{
public:
int x;

C – Questions

1. What is the output of the following code
main()
{
printf(“Hello %d”,printf(“QUARK test? “));
}
a. Compile time error.
b. Hello QUARK test?
c. Run time error.
d. None of the above.
e. Quark Test ?Hello.

Ans. d. the output is QUARK test? Hello 12
This is because the evaluation of the parameters in a function call is done from right to left, becz the parameters were passed via a stack hence the first parameter (the leftmost one) is at the bottom of the stack and the rightmost parameter (if it is an expresseion, it will be evaluated before putting it on the stack) is on the top of the stack, hence while popping the parameters from the stack, the function printf (or any other function) gets them in the reverse order, i.e., from right to left, hence the statement printf(“Quark test? “) gets evaluated first while pushing it as a parameter on to the stack, and then the statement printf(“Hello %d”) is executed. The ’12′ is the result of the return of printf(“Quark test? “) which returns the number of characters printed.

2.) Out put of the following code is

}
a. Compilation error.
b. Run-time error
c. Continuous scrolling Quark on the screen.

6) What shall be the output of the following code ?
#define f(x) x*x*x

main(){
printf(“\n%d”,f(2+2));
}
a. 8

void main()
{ int x=3;
printf(“%d\t %d”,x>>1, x<<3);
}
a. 1 and 4
b. 1 and 24
c. 1 and 27
d. None of the above

Ans. 1 and 24
This is because 3 in binary is 00000000 00000011 in two bytes (integer). Again, the right to left evaluation rule of parameters is applicable and so x<<3 gets executed first, it means left shift 3 times, but this operator does not change the value of x itself, it simply returns a value, so x retains its value after this operation has been carried out, so we get 00000000 00011000 which is 24, so 24 is pushed onto the stack, and then x>>1, right shift 1, 00000000 00000011, which is 1 in decimal, so 1 is pushed onto the stack, then printf(“%d\t %d”) gets executed displaying 1 24.

x =(int *) 15;
a. Compilation error
b. Compiles but gives a runtime error

10. Which of the following functions cannot be called from another file?

a. const void func(){ ……..}
b. extern void func(){………}
c. void func(){………}
d. static void func(){……….}

Ans. static

11. What will be the out come of the following code?

#include

int * func(){
static int x=0;
x++; return &x;
}
int main()
{
int * y = func();
printf(“%d”,(*y)++);
func();
printf(“%d\n”,*y);
return 0;
}

a. Compilation error.
b. Prints 1 and 3
c. Prints 1 and 3 but it is not good practice.
d. Prints 1 and 1
e. The code will not execute properly because y points to a variable whose life span is limited to execution of the function func();

Ans. Prints 1 and 3 but it is not a good practice

12. Referring to the above code , which of the following would be the correct
implementation for myFunc ?
char *format = “%d”;
int main()
{
int x;
myFunc(scanf,&x);
printf(“%d\n”,x);
return(0);
}

a. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,&x);}
b. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,*x);}
c. void myFunc(int*y(const char*,…),int *x) {(*y)(format,&x);}
d. void myFunc(*(int y(const char*,…)),int *x) {(*y)(format,x);}
e. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,x);}

13. What shall be the output of the following C code?
void main()
{
unsigned int x= -1;
int y =0;
if(y<=x) printf(“A is true\n”);
if (y = =(x = -10)) printf(“B is true\n”);
if ((int) x>=y) printf(“C is true\n”);
}
a. A is true.
b. B is true.
c. C is true.
d. None of the above.

Ans. A is true because x contains -1, i.e., in binary it is ffff, i.e., all 1s, so being unsigned, all 1s are interpreted as the value 65535 and not as -1 (however, all 1s are interpreted as -1 if it is just an int), hence y<=x returns true.

14. In the following code what is the correct way to increment the variable ptr to
point to the next member of the array

union intfloat
{
int intArray[ 5];
float floatArray[ 5];

};
union intfloat arr[20];
void *ptr =arr;

a. ++(int*)ptr;
b. ptr = ptr+5;
c. ptr = ptr +sizeof(*ptr);
d. ptr = ptr+sizeof(intfloat.floatArray);
e. ptr = (void*)((union intfloat*)ptr +1);

Ans. e. ptr = (void*)((union intfloat*)ptr +1);

15.What shall be the output of the following program?

#define PRINTXYZ(x,y,z) printf (#x “=%d\t” #z “=%d\n”, x, y)

void main() {
int x, y, z;
x=0; y=1; z=2;

x || ++y ||++z;
PRINTXYZ(x,y,z);

++x || ++y && ++z;
PRINTXYZ(x,y,z);

++x && ++y || ++z;
PRINTXYZ(x,y,z);
}

a. Compilation error.
b. Runtime error.
c.
x=0 z=2
x=1 z=3
x=2 z=4
d.
x=0 z=2
x=1 z=2
x=2 z=3
e. None of the above.

Ans. d.

16. What shall be the output of the following code ?

main()
{
printf(“%d %d”, sizeof(NULL), sizeof(“”));
}

a. 1 and 0.
b. 0 and 1
c. 2 and 1
d. 4 and 1
e. None of the above

Ans. Depends on the machine and compiler. Actually it is the sizeof(int) and sizeof(char) as a string is stored as a char array terminated with 0, so sizeof(“”) gives 1, whereas sizeof(“adsf”) gives 5 (including the terminating 0). So in TurboC we get c as the answer, on VC we get d as the answer, so I guess e is the ans, i.e., None of the above.

17. What shall be the output of the following code?

int *check ( int,int);
void main()
{int c,d;
c = check(11,29);
d= check(20,30);
printf(“\nc=%u”,c);
}
int * check(int i,int j )
{
int *p, *q;
p=&i;
q=&j;
if(i>=95)
return(q);
else
return(p);
}
a. 11
b. 29
c. Compilation error
d. Runtime error
e. None of the above.

Ans. e. None of the above. the statement c = check(11,29) is assigning an int ptr to an int, so c has an address of an int (which has gone out of scope, since the function returns the address of a variable which had its scope only inside the function, since the parameters were passed by value) so the value printed can be anything. Instead, if the statement was c = *(check(11,29)) then c would have the value stored at the address returned by the function, which would most probably be 11, but it cannot be guaranteed since the variable i has fallen out of scope.

18. What shall be the output of the following code?

void main()
{int a[3][2]={ 1,2,
5,7,
6,8};

printf(“\n%d”,((a+1)-(&a+1)));
}
a. 0
b. -16
c. -2
d. -8
e. None of the above.

Ans. -2. I haven’t been able to figure this one out. a is the address of the 2-d array, here a, &a, *a all give the same value, i.e., address of the array. (a+1) gives the address of the second row, it is the same as a[1]. *(a+1) gives the address of the first cell of the second row. **(a+1) gives the value of the element stored in the first cell in the second row. (*(a+1)+1) gives the address of the second cell of the second row. *(*(a+1)+1) gives the value of the element stored in the second cell in the second row.

19.What shall be the output of the following code?
main()
{
char str1[]=”Hello”;
char str2[]=”Hello”;
if(str1= =str2&& (*(str1+6)= =*(str2+6)))
printf(“\n Equal”);
else
printf(“\n unequal”);
}
a. Equal
b. Unequal
c. Compilation error.
d. Runtime error.
e. None of the above.

Ans. b. Unequal, because the addresses of the two strings are str1 and str2 and they are different.

20. Given that sizeof(int) is 2 , what is the output of the following code
main()
{
int a, b=255,c=127;
a=~b;
c=c^(~a & b|0);\
c=c^(~(~b));
printf(“%d\n”,c);
}
a. Error because of overflow;
b. 255
c. -256
d. 127
e. None of the above

Ans. d. 127
