    Angry Simple while loop

    Sorry to be wasting your time with this simple problem, but I'm in my first class and am stumped on a while loop.

    Here is what I have:

    #include <iostream> 
    int main() {
       int i = 100;
        while (i <= 150){
          cout << i << " ";
           i = i + 2;}
    return 0;}

    The program runs just fine, but the numbers all appear on one line. I need to have only 6 per line, for example 100 102 104 106 108 110
    112 114 116 etc.... to 150

    Keep in mind I have to use a while loop. I know I need to add another variable somewhere in that loop but I cant figure out the syntax I need to use. Can someone give me a push in the right direction? Thank you very much.

    First of all this is C++ not C, so please post under the appropriate forum. Admins will probably move the thread there.

    Secondly, all you need is another variable, let's call it x that you initialize to 0 before the loop. Then, inside the loop you increment and test if it's new value % 6 == 0. That means that the variable value has reached a value which is a multiple of 6 and it's time to print an endline:

    i.e. cout << endl;
