for loop assistance

[Vanniekerk789]

Hi, I got an assignment that I need some help with? I need to include this for loop in a program and it should excuted 10 times. I'm noy sure what the 'X' means. and where to start when including it in a program. Any guide lines?

  for (int i = 1; i <= n; i = i + 3)
cout << 'X';

You can just put it in your main function:

int main()
{
    int n = 10;
    for (int i = 1; i <= n; i = i + 3)
         cout << 'X';
    //...
}

This just ouputs the character X:

1 2

cout << 'X';

Output: X

Also, instead of:
i = i + 3
You can just use:
i +=3

How can I make this code excute 10 times without changing anything on it?

I'm sorry, I'm not sure what you mean.

The code I gave above isn't the full source code, just a portion of the code that has the for loop. I can't do all of your homework for you. I can only help you with your problems that you are having. If this is the case, your code should be something like this:

// Your includes

int main()
{
    int n = 10;
    for (int i = 1; i <= n; i = i + 3)
         cout << 'X';
    //...
}

int main()
{
    int n = 10;
    for (int i = 1; i <= n; i = i + 3)
         cout << 'X';
    //...
}

This will only execute 4 times, since i is being incremented by 3. You need to either increment i by only 1 (++i) or have n = 30.
