    Need help with simple programs...

    We're doing review of last year's programming, and I can't figure them out!! I know they have to be easy. Please help me get started:

    1. Write a program that uses FOR loops to produce the following pattern:

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

    (I hope it turns out like I typed it)


    2. Used NESTED FOR LOOPS to produce the following numbering on the screen:

    1

    1
    2

    1
    2
    3

    1
    2
    3
    4

    Okay, the first one didn't turn out like I wanted it to be, it should be a big X but with asterisks.

    These are really easy. I could solve them both in 5 minutes... but that would take all the thinking away from you.

    Think about nested for loops, and it should become pretty clear.

    eh

    Okay, thanks, you didn't help me at all. You see, I already know all this crap, but I forgot over the summer. Sounds stupid, but it's true.

    eh?

    maybe you should retake the previous course. this stuff is really easy, and we're under no obligation to DO other's homework. Post some code, and show us you give half a crap...

    I have

    for (a = 0; a < 9; a++)
    {
    cout<<"*";
    }


    Nah, I don't need to take the course again. It'll come back to me hopefully.

    Can someone at least help me get started? I do alot better from learning from other people's code.

    Here's a start. You don't have any nested for loops. You will also need to cout some blank spaces on the X problem. On part of the X you'll need to increment, on the other decrement (at least that's one way to do it).

    Code:
    #include<iostream>
    #define MAX 5
    
    int main()
    {
    	int i_loops;
    
    	for(int i=0; i< MAX;i++)
    	{
    		i_loops = 0;
    		while(i_loops++ < i) std::cout << ("%d",i_loops) << std::endl;
    
    		if(i != 0) std::cout << std::endl;
    	}
    	return 0;
    }
    Here is a way to do it without nested 'for' loops. HAHAHAHAHAHA

    ("%d",i_loops) is unnecessary in c++...... you just cout<<i_loops and it will work fine.....
    Free the weed!! Class B to class C is not good enough!!
