What will be the output of the following program?

#include<iostream.h> 
class CuriousTabTest
{
    public:
    CuriousTabTest(int &x, int &y)
    {
        x++;
        y++;
    } 
};
int main()
{
    int a = 10, b = 20;
    CuriousTabTest objBT(a, b); 
    cout<< a << " " << b; 
    return 0; 
}

#include<iostream.h> 
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; 
}
