Program to enter the principal, rate & time and print the simple interest

#include <iostream.h>
#include <conio.h>

void main()
{
clrscr();
int x;
float sinterest,principal,rate,time;
for(x=4;x>=0;x--)
{
cout << "Enter the principal, rate & time : " << endl;
cin>>principal>>rate>>time;
sinterest=(principal*rate*time)/100;
cout << "Principal = $" << principal << endl;
cout << "Rate = " << rate << "%" << endl;
cout << "Time = " << time << " years" << endl;
cout << "Simple Interest = $" << sinterest << endl;
}
getch();
}

This program takes in the prinicipal, rate and time as a screen input from the user.
The program is executed (run) 5 times using the 'FOR' loop.
It calculates the simple interest using the formula I = PTR/100.
The principal, rate, time and the simple interest are then outputted using the 'cout' command.

 SAMPLE INPUT
1000 5 3

 SAMPLE OUTPUT
Principal = $1000
Rate = 5%
Time = 3 years
Simple Interest = $150
