Answer: Option D

#include
class PowerFinder
{
public:
void Power(int x = 1, int y = 1)
{
int P = 1, i = 1;
while(++i <= y) { P *= x; } cout<< P << endl; } }; int main() { PowerFinder FP; FP.Power(2, 6); return 0; }

[A].The program will print the output 12.
[B].The program will print the output 16.
[C].The program will print the output 32.
[D].The program will print the output 36. 

Answer: Option C

#include
void Tester(int xx, int yy = 5);
class IndiaBix

Answer: Option C

#include
long FactFinder(long = 5);
int main()
{
for(int i = 0; i<= 0; i++) cout<< FactFinder() << endl; return 0; } long FactFinder(long x) { if(x < 2) return 1; long fact = 1; for(long i = 1; i <= x-1; i++) fact = fact * i; return fact; }

[A].The program will print the output 1.
[B].The program will print the output 24.
[C].The program will print the output 120.
[D].The program will print the output garbage value. 

Answer: Option B

#include
class IndiaBix
{
public:
void Bix(int x = 15)
{
x = x/2;
if(x > 0)
Bix();
else
cout<< x % 2; } }; int main() { IndiaBix objIB; objIB.Bix(); return 0; }

[A]. The program will display 1.
[B]. The program will display 2.
[C]. The program will display 15.
