Answer: Option C

#include
class Addition
{
int x;
public:
Addition()
{
x = 0;
}
Addition(int xx)
{
x = xx;
}
Addition operator + (int xx = 0)
{
Addition objTemp;
objTemp.x = x + xx;
return(objTemp);
}
void Display(void)
{
cout<< x << endl; } }; int main() { Addition objA(15), objB; objB = objA + 5; objB.Display(); return 0; }

[A].The program will print the output 20.
[B].The program will report run time error.
[C].The program will print the garbage value.
[D].Compilation fails due to 'operator +' cannot have default arguments.

Answer: Option C

#include
class IndiaBix
{
int x;
float y;
public:
IndiaBix(int x)
{
x = x;
}
IndiaBix(int p = 0, int q = 10)

{
cout<< x; } }; int main() { int val = 12; IndiaBix objBix(val); IndiaBix objTmp(); objBix.SetValue(val, 3.14f); objBix.Display(); return 0; }

[A].The program will print the output 2.
[B].The program will print the output 12.
[C].The program will report run time error.
[D].The program will not compile successfully. 

Answer: Option D

#include

{
int x, y, z;
public:
void Apply(int xx = 12, int yy = 21, int zz = 9)
{

z = x -= 2;
}
void Display(void)
{
cout<< x << " " << y << endl; } void SetValue(int xx, int yy) { Apply(xx, 0, yy); } }; int main() { IndiaBix *pBix= new IndiaBix; (*pBix).SetValue(12, 20); pBix->Display();

[A].10 10
[B].12 10
[C].12 21
[D].12 31 

Answer: Option A

#include
class Base
{
int x, y, z;
public:
Base()
{
x = y = z = 0;
}
Base(int xx, int yy = 'A', int zz = 'B')
{
x = xx;
y = x + yy;
z = x + y;
}
void Display(void)
{
cout<< x << " " << y << " " << z << endl; } }; class Derived : public Base { int x, y; public: Derived(int xx = 65, int yy = 66) : Base(xx, yy) { y = xx; x = yy; } void Display(void) { cout<< x << " " << y << " "; Display(); } }; int main() { Derived objD; objD.Display(); return 0; }

[A].The program will report compilation error.
[B].The program will run successfully giving the output 66 65.
[C].The program will run successfully giving the output 65 66.
[D].The program will run successfully giving the output 66 65 65 131 196. 

Answer: Option C

#include

A = y + 1 - 1;
M = z - 1;
}
void Display(void)
