#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;
 }

Answer 2

#include <stdio.h>
main()
{
  int row, H , j ;
 
      printf("Height of triangle:  "); 
      scanf("%d", &H);
      for (row=1; row <= H ; row++ )
             for (j = row; j >= 1 ; j--)      // print integers, starting from row number up to 1
                   printf("%d  ", j);
    
}
