Write a C++ program to demonstrate default arguments with a simple example.

Program Code:

#include<iostream.h>

int main()

{

float amount;

float value(float p,int n,float r=0.15);

amount=value(500.00,5);

cout<<"\nFinal Value="<<amount<<"\n";

amount=value(1000.00,5,0.30);

cout<<"\nFinal Value="<<amount<<"\n";

return 0;

}

float value(float p,int n,float r)

{

int year=1;

float sum=p;

while(year<=n)

{

sum*=(1+r);

year+=1;

}

return sum;

}
