first thing that I spotted is that you only passed in an array when you invoke call fuction

y is there a ; after if statement in line 24?

I believe you can use the coefficient formula.

you can try: if first = last or if last = 0 then counter ++

confusion 1: Loop used to test if i is divisible by any number, the condition j<=(i/j) is used so that numbers wont be checked twice. if no number is divisible, then the loop will not break in between result j>(i/j)

maybe you can try to check then string length then check if its alpha or not.

try [CODE] for (i = 1; i <= lines; i++){ cout <<i; for(j = 1; j <= i; j++) // calculation to print start cout <<"*"; cout<<endl; }[/CODE]
