Which of the following statement is correct about the program given below? 
#include<iostream.h>
const double BixConstant(const int, const int = 0);
int main()
{
    const int c = 2 ;
    cout<< BixConstant(c, 10)<< " "; 
    cout<< BixConstant(c, 20)<< endl; 
    return 0;
}
const double BixConstant(const int x, const int y)
{
    return( (y + (y * x) * x % y) * 0.2);
}
The program will print the output 2 4.
The program will print the output 20 40.
The program will print the output 10 20.
The program will print the output 20 4.50.
The program will report compile time error.

Here, in the first call x=2 and y=10.

So it returns, (10+(10*2)*2%10)*0.2;
=(10+20*2%10)*0.2;
=(10+40%10)*0.2;
=(10+0)*0.2;
=10*0.2;
=2.

In the second call, x=2 and y=20.

So it returns, (20+(20*2)*2%20)*0.2;
=(20+40*2%20)*0.2;
=(20+80%20)*0.2;
=(20+0)*0.2;
=20*0.2;
=4.

Error because function definition of one function is not present as cpp is strict type checking. So compile time error.

Can arguments override constant parameters?

If yes why we call them constants?
