Write a c program to find out NCR factor of given number

#include<stdio.h>

#include<conio.h>

int main()

{  

int n,r,ncr; 

 printf("Enter any two numbers->"); 

 scanf("%d %d",&n,&r);  

ncr=fact(n)/(fact(r)*fact(n-r));  

printf("The NCR factor of %d and %d is %d",n,r,ncr);  

return 0;

} 

int fact(int n)

{  

int i=1;  

while(n!=0){     

 i=i*n;     

 n--;  

} 

 return i; 

}
