Triangle Star Pattern C Program

#include<stdio.h>

int main()
{
  int i, j, n;
  printf("Enter your triangle pattern size:");
  scanf("%d", &n);
  
  for(i=0; i<=n; i++)
  {
    for(j=0; j<=n-1-i; j++)
       printf(" "); 
    for(j=0; j<i; j++)
       printf("* "); 
    printf("\n"); 
  }
  return 0;
}

Program output for Execution 1:

Enter your triangle pattern size:3       
   * 
  * *
