    So now you produce the first line. So it looks like you'll need to produce the same line num_1 times. Looks like a job for another loop which includes your current loop doesn't it. Have a think about that.

    BTW, you have, quite correctly declared your main() as int, you should return an int at the end of your program. Add a

    return 0;

    after the pause.

    Nest the while loop:

    Code:
    for (int i = 0; i < num_1; i++)
    {
        while (counter <= num_1) 
        { 
        counter++; 
        printf("*"); 
        } 
    
        printf("\n");  
        /* or "\r" or whatever you use for newline (hex - 0x0d0a) */
        counter = 1;
    }
    **Edit - Sorry adrianxw, didn't realize you had already responded.
