Write a program in c to calculate the simple interest.

#include<stdio.h>
int main()
{
int p,t;
float r,si;
printf("Enter the principle\n");
printf("Enter the rate\n");
printf("Enter the time\n");
scanf("%d",&p);
scanf("%f",&r);
scanf("%d",&t);
si=(p*r*t)/100;
printf("simple interest=%f",si);
return 0;

}
