Coin counting (logic problem)

**xlokix** · 01-19-2005

Ok I have one little problem and that's all I'm asking out of these forums (for now at least)!

I have a project that I have to do, you have to display this with loops:

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

Now you can't just write

Code:

cout << "*\n";
cout << "**\n";

etc.
I'm supposed to write it with loops. This is all I have so far, and all I can get is a row of *'s going vertical :\ Sorry for asking so many questions, but it's probably a simple project, I've just never done anything like this before.

Code:

#include <iostream.h>
#include <stdio.h>

main()
{
      int asterisks = 0; 
      do
      {
      cout << "*\n"; 
      asterisks++;
      }
      while (asterisks < 6);
      getchar();getchar();
      return 0;
}

Why don't you look into using for()?

Code:

for (int x = 0; x < MAX_STARS; x++)
{
    // Your code for handling the loop here
}

Edit: I'll be nice and give another hint.

Your life will be a lot easier if you insert a while() loop into your for() loop. Allow me yet another example.

Code:

 #define MAX_STARS 6

// int main() stuff..

int y = 0;

for (int x = 0; x < MAX_STARS; x++)
{
    while (y <= x)
    {
        // Handle your std::cout and y increment here
    }
}

Edit 2: I just played around with code for a second and made up a function to do something like this:

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

Only go to the following link if you are truly and completely stumped on the problem: http://lithorien.net:5001/test.cpp

Actually, for the test that was today, there were 3 programs I had to know, and one of them would be on the test. Thankfully, one of the three programs on it was the one I knew (the asterisks one being the 3rd the one i didnt know). So I don't need it anymore, thanks for the help anyway D:
Looks simpler than I thought.
