C program to find greatest among three numbers using function.

#include<stdio.h>

#include<conio.h>

main(){

float i,j,k,ans;

float greatest(float a,float b,float c);

clrscr();

printf("Enter values of i,j,k\n");

scanf("%f%f%f",&i,&j,&k);

ans=greatest(i,j,k);

printf("%f is greatest\n",ans);

getch();

return 1;

}

float greatest(float a,float b,float c){

if(a>b){

if(a>c) return a;

else return c;

}

else{

if(b>c) return b;

else return c;

}
