#include
int BixTest(int x, int y);
int BixTest(int x, int y, int z = 5);
int main()
{
cout<< BixTest(2, 4) << endl; return 0; } int BixTest(int x, int y) { return x * y; } int BixTest(int x, int y, int z = 5) { return x * y * z; }

[A].The program will print the output 5.
[B].The program will print the output 8.
[C].The program will print the output 40.
[D].The program will report compile time error. 

Answer: Option D

#include
class IndiaBix
{
public:
int x, y;
IndiaBix(int xx = 10, int yy = 20)
{
x = xx;
y = yy;
}
void Exchange(int *, int *);
};
int main()
{
IndiaBix objA(30, 40);
IndiaBix objB(50);
objA.Exchange(&objA.x, &objB.y);
cout<< objA.x << " " << objB.y << endl; return 0; } void IndiaBix::Exchange(int *x, int *y) { int t; t = *x; *x = *y; *y = t ; }

[A].20 10
[B].30 20
[C].20 30
[D].30 40 

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.
[D]. The program will go into an infinite loop. 

Answer: Option D

#include
long BixFunction(int x, int y = 5, float z = 5)
{
return(++x * ++y + (int)++z);
}
int main()
{
cout<< BixFunction(20, 10); return 0; }

[A].237
[B].242
[C].240
[D].35 

Answer: Option A

#include
class BixArray
{
int Matrix[3][3];
public:
BixArray()
{
for(int i = 0; i<3; i++) for(int j = 0; j < 3; j++) Matrix[j][i] = i + j; } void Display(void) { for(int i = 0; i < 3; i++) for(int j = 0; j < 3; j++) cout<< Matrix[j][i] << " "; } }; int main() { BixArray objBix; objBix.Display(); return 0; }

[A].The program will display the output 4 3 2 3 2 1 2 1 0.
[B].The program will display the output 0 1 2 1 2 3 2 3 4.
[C].The program will display the output 9 garbage values.
[D].The program will report error on compilation.
