C Program For Print A Left Pascal Triangle Using Number

#include<stdio.h>

long fact(int);

int main()
{
    int counter,i,j;

    printf("Enter The No. Of Terms You Want To Print: ");
    scanf("%d",&counter);

    for(i=0;i<counter;i++)
 {    
  printf(" ");
         for(j=0;j<=i;j++)
             printf("%ld ",fact(i)/(fact(j)*fact(i-j)));
         printf("\n");
    }
    
    return 0;
}
//function starting 
long fact(int num)
{
    long f=1;
    int i=1;
    while(i<=num)
 {
         f=f*i;
         i++;
  }
  return f;
  //funtion returning a value 
 }

Output:
