Problem # 25:
Write a program that inputs principal amount, rate of interest and total time. It
calculates the compound interest and displays it.
Solution:
#include<iostream>
#include<conio.h>
#include<math.h>
using namespace std;
int main()
{
float p, r, t, ci; //prinipal ammount, rate of interest, time, compound interest;
cout<<"Enter principal amount";
cin>>p;
cout<<"Enter rate of interest";
cin>>r;
cout<<"Enter total time";
cin>>t;
ci=p*pow(1+(r/100),t);
cout<<"Compound Interest: "<<ci<<endl;
getch();
return 0;
}
