Answer 2

Answer:

#include<stdio.h>

int main()

{

  int N, r, i, RESULT;

  int fact1, result1 = 1, fact2, result2 = 1, fact3, result3 = 1;

  scanf("%d", &N);

  scanf("%d", &r);

  for(i = N; i >= 1; i--)

  {

    fact1 = i;

    result1 = (fact1*result1);

  }

  printf("N = %d\n", result1);

  for(i = r; i >= 1; i--)

  {

    fact2 = i;

    result2 = (fact2*result2);

  }

  printf("R = %d\n", result2);

  for(i = (N-r); i >= 1; i--)

  {

    fact3 = i;

    result3 = (fact3*result3);

  }

  printf("N-r = %d\n", result3);

  RESULT = (result1/(result2*result3));

  printf("nCr = %d", RESULT);

   return 0;

}
