    problem with 'for' loop

    Here's the deal. I have to create a program that outputs a pic like the one below using a 'for' loop.

    *
    **
    ***
    ****
    *****
    ******
    *******
    ********
    *********
    **********

    No input required for this program and in order to get the *'s up there all u can use is a cout statement involving "*". Then i have to produce the same pic again 3 times, but have it turned around in the 3 different directions it can be turned. I need some help with this and any u can give is appericiated. Thanks to all!

    Hint: a for loop which prints one line in each pass and keeps track of how many *'s to print in each line. Inside the for loop, another for loop that prints each line. That's the first pic.

    I thought there might be a loop inside of a loop and I know i need a counter to keep track, but I don't know the coding on how to get the stars to add one on every print until it reaches 10

    this is all i can come up with:

    for( int counter=1; counter <= 10; counter++ )
    cout << "*" << endl;

    All 4 pics involve 2 nested for loops. The outer loop corresponds to going down, the inner loop corresponds to going across.

    Edit: Also note that in the inner loop, you only use cout << "*". You don't use cout << endl until after the inner loop (but still inside the outer one).

    OK, i did something like that using a 'while'statement but it was a box that looked like this...

    Code:
    ************
    *                    *
    *                    *
    *                    *
    ************

    sorry the line in the middle is supposed to be on the very end

    Use [code][/code] tags when posting code or the pictures that you are trying to show so that they retain their formatting.
