What will be the output of the following program?

#include<iostream.h>
double CuriousTabFunction(double, double, double = 0, double = 0, double = 0);
int main()
{
    double d = 2.3;
    cout<< CuriousTabFunction(d, 7) << " ";
    cout<< CuriousTabFunction(d, 7, 6) << endl;
    return 0; 
}
double CuriousTabFunction(double x, double p, double q, double r, double s)
{
    return p +(q +(r + s * x)* x) * x;
}

#include<iostream.h> 
int CuriousTabFunction(int m)
{
    m *= m;
    return((10)*(m /= m)); 
}
int main()
{
    int c = 9, *d = &c, e;
    int &z = e;
    e = CuriousTabFunction(c-- % 3? ++*d :(*d *= *d));
    z = z + e / 10;
    cout<< c << " " << e;
    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; 
}
