C++ Exercises: Calculate Compound Interest
C++ Basic: Exercise-55 with Solution
Write a program in C++ to enter P, T, R and calculate Compound Interest.
Sample Solution:
C++ Code :
#include<iostream>
#include<math.h>
using namespace std;
int main()
{
float p,r,t,cp,ci;
cout << "\n\n Calculate the Compound Interest :\n";
cout << " -------------------------------------\n";
cout<<" Input the Principle: ";
cin>>p;
cout<<" Input the Rate of Interest: ";
cin>>r;
cout<<" Input the Time: ";
cin>>t;
ci=p*pow((1+r/100),t)-p;
cp=p*pow((1+r/100),t);
cout<<" The Interest after compounded for the amount "<<p<<" for "<<t<<" years @ "<<r<<" % is: "<<ci;
cout << endl;
cout<<" The total amount after compounded for the amount "<<p<<" for "<<t<<" years @ "<<r<<" % is: "<<cp;
cout << endl;
cout << endl;
return 0;
}
Sample Output:
Calculate the Compound Interest : ------------------------------------- Input the Principle: 20000 Input the Rate of Interest: 10 Input the Time: 1.5 The Interest after compounded for the amount 20000 for 1.5 years @ 10 % is: 3073.8 The total amount after compounded for the amount 20000 for 1.5 years @ 10 % is: 23073.8
