[A].0
[B].314
[C].314.0000
[D].200.0000 

Answer: Option A

#include
long GetNumber(long int Number)
{
return --Number;
}
float GetNumber(int Number)
{
return ++Number;
}
int main()
{
int x = 20;
int y = 30;
cout<< GetNumber(x) << " "; cout<< GetNumber(y) ; return 0; }

[A].The program will print the output 19 31.
[B].The program will print the output 20 30.
[C].The program will print the output 21 31.
[D].The program will print the output 21 29. 

Answer: Option C

#include
struct MyStructure
{
class MyClass
{
public:
void Display(int x, float y = 97.50, char ch = 'a')
{
cout<< x << " " << y << " " << ch; } }Cls; }Struc; int main() { Struc.Cls.Display(12, 'b'); return 0; }

[A].The program will print the output 12 97.50 b.
[B].The program will print the output 12 97.50 a.
[C].The program will print the output 12 98 a.
[D].The program will print the output 12 Garbage b. 

Answer: Option C

#include
int main()
{
float Amount;
float Calculate(float P = 5.0, int N = 2, float R = 2.0);
Amount = Calculate();
cout<< Amount << endl; return 0; } float Calculate(float P, int N, float R) { int Year = 1; float Sum = 1 ; Sum = Sum * (1 + P * ++N * R); Year = (int)(Year + Sum); return Year; }

[A].21
[B].22
[C].31
[D].32 

Answer: Option D

#include
static int b = 0;
void DisplayData(int *x, int *y = &b)
{
cout<< *x << " " << *y; } int main() { int a = 10, b = 20 ; DisplayData(&a, &b); return 0; }

[A].The program will print the output 10 20.
[B].The program will print the output 10 0.
[C].The program will print the output 10 garbage.
[D].The program will report compile time error. 

Answer: Option A

#include
class IndiabixSample
{
private:
