#include<stdio.h>

long fact(int);

int main(){

    int line,i,j;

    printf("Enter the no. of lines: ");

    scanf("%d",&line);

    for(i=0;i<line;i++){

         for(j=0;j<line-i-1;j++)

             printf(" ");

         for(j=0;j<=i;j++)

             printf("%ld ",fact(i)/(fact(j)*fact(i-j)));

         printf("\n");

    }

    return 0;

}

long fact(int num){

    long f=1;

    int i=1;

    while(i<=num){

         f=f*i;

         i++;

  }

  return f;

 }

Sample output:

Enter the no. of lines: 8

       1
