C Program to calculate the value of nCr,n≥r using function

#include<stdio.h>
int fact(int);
void main()
{

 printf("Enter the value of n & r (n>=r) for nCr: ");
scanf("%d,%d",&n,&r);
if(n>=r)
{

                 //The formula is: nCr=n!/(r!*(n-r)!)
  printf("\n\nThe value of %dC%d is: %d",n,r,c);

}
