[D]. The program will print the output 11 21.
 
Answer: Option B

#include
class BixBase
{
int x;
public:
BixBase(int xx = 0)
{
x = xx;
}
void Display()
{
cout<< x ; } }; class BixDerived : public BixBase { int y; public: BixDerived(int yy = 0) { y = yy; } void Display() { cout<< y ; } }; int main() { BixBase objBase(10); BixBase &objRef = objBase; BixDerived objDev(20); objRef = objDev; objDev.Display(); return 0; }

[A].0
[B].10
[C].20
[D].Garbage-value 

Answer: Option C

#include
int main()
{
int m = 2, n = 6;
int &x = m++;
int &y = n++;
m = x++;
x = m++;
n = y++;
y = n++;
cout<< m << " " << n; return 0; }

[A].The program will print output 3 7.
[B].The program will print output 4 8.
[C].The program will print output 5 9.
[D].The program will print output 6 10.

Answer: Option E

#include
int main()
{
int m = 2, n = 6;
int &x = m;
int &y = n;
m = x++;
x = m++;
n = y++;
y = n++;
cout<< m << " " << n; return 0; }

[A].The program will print output 2 6.
[B].The program will print output 3 7.
[C].The program will print output 4 8.
[D].The program will print output 5 9. 

Answer: Option C

[A].The program will print the output 5 6 7 8 9 10.
[B].The program will print the output 5 6 7 8 9 10 7.
[C].The program will print the output 5 7.
[D].It will result in a compile time error. 

Answer: Option C

#include
class IndiaBix
{
int x, y;
public:
IndiaBix(int xx = 0, int yy = 0)
{
x = xx;
y = yy;
}
void Display()
{
cout<< x << " " << y; } IndiaBix operator +(IndiaBix z) { IndiaBix objTemp; objTemp.x = x + z.x; objTemp.y = y + z.y; return objTemp; } }; int main() { IndiaBix objBix1(90, 80); IndiaBix objBix2(10, 20); IndiaBix objSum; IndiaBix &objRef = objSum; objRef = objBix1 + objBix2; objRef.Display(); return 0; }

[A].It will result in a runtime error.
[B].It will result in a compile time error.
[C].The program will print the output 9 4.
[D].The program will print the output 100 100.
