a C Program to generate binomial coefficient for B(n,r) usin

#include<stdio.h>
int bi_coeff(int a);
void main()
{
    int n;
    printf("Enter the number of rows: ");
    scanf("%d",&n);
    bi_coeff(n);
}
int bi_coeff(int a)
{
    int i,j,result=1;
    for(i=0;i<a;i++)
    {
        for(j=0;j<=i;j++)
        {
            if(i==0||j==0)
                result=1;
            else
                result=(result*(i-j+1))/j;
            printf("%d ",result);
        }
        printf("\n");
    }
