Write a function to input amount, rate, time and print simple interest.

#include <stdio.h>
#include <conio.h>
float       interest ( float, float, float );                /* Function prototype declaration */
void main ( )
{     
        float       amt, rat, tim;

        clrscr ( );
                            
        printf("\n\n\t\t Enter amount.............:"); scanf("%f", &amt);
        printf("\n\n\t\t Enter rate of interest...:"); scanf("%f", &rat);
        printf("\n\n\t\t Enter time duration......:"); scanf("%f", &tim);
                                
        sud = interest ( amt, rat, tim );                       /* Function calling */
                                                         
        printf("\n\n\t\t INTEREST = % .2f", sud);
        getch ( );
}                         
                            
float  interest ( float    x, float    y, float    z )           /* Function Definition */

        float       w;
        w = ( x * z ) * y / 100.0;
        return ( w );
