Write A Program for calculating NCR using Functions

# include<stdio.h>

#include<conio.h>

void main ( )

{

int n, r, ncr, a, b, c;

clrscr( ) ;

int fact ( int);

printf (“enter n, r values”);

scanf ("%d%d”, & n, & r);

a = fact (n);

b = fact (r);

c= fact (n-r);

ncr = a/b*c;

printf (“\n ncr value is %d”, ncr );

getch ( );

}

int fact ( int x)

{

int i, y=1;

for ( i = 1; i < = x; i ++)

y = y * i;

return ( y);
