C++ Program Calculate Simple Interest

#include<iostream>
using namespace std;
int main()
{
	int p,r,t,i;
	cout<<"Enter Principle : ";
	cin>>p;
	cout<<"Enter Rate : ";
	cin>>r;
	cout<<"Enter Time : ";
	cin>>t;
	i=(p*r*t)/100;
	cout<<"Simple interest is : "<<i;
	return 0;
}

OUTPUT:

Enter Principle : 1800
Enter Rate : 5
Enter Time : 3
Simple interest is : 270
