Find the simple interest

/* Write a C program to find the simple interest , given principle, *
* rate of interest and times*/

#include stdio.h
#include conio.h

void main()
{

float p, r, si;
int t;

clrscr();

printf("Enter the values of p,r and t\n");
scanf ("%f %f %d", &p, &r, &t);

si = (p * r * t)/ 100.0;

printf ("Amount = Rs. %5.2f\n", p);
printf ("Rate = Rs. %5.2f%\n", r);
printf ("Time = %d years\n", t);
printf ("Simple interest = %5.2f\n", si);

}

/*-----------------------------
Output
Enter the values of p,r and t
2000
8
3
Amount = Rs. 2000.00
Rate = Rs. 8.00%
Time = 3 years
Simple interest = 480.00

This is a pretty straight forward example which uses the basic mathematical formula for calculation. The only new thing to note here is %5.2f which is dealt in previous example.
