You're including the question of how many numbers inside the loop. Try taking this two lines outside the for: cout << "How many numbers will you be entering (up to 20): " <<endl; cin >> num0; That way the program will loop only the "Enter a number" part, for the 0 > num0 (specified input) part.

Now I'm working on this part: Finally print the numbers in reverse, separated by a comma and a single space, on a single line.

I think I just have to create a loop counting down right?

You're welcome lol =) For that last part, in Java I would do: for(int i = array.length; i >= 0; i){ System.out.print(array[i]+", "); }

Yep, just start at the end and go down to 0, and either store it in a String variable, or directly print it without jumping lines

Why did you write array[i]+?

It's Java, + is used to put together two strings [or a number and a string]. array[i] + " hello" would print: "21 hello" (assuming the number in array[i] was 21)

Hmm I'm wondering what to put into my cout function... it would be the array with the new numbers...

for(int i = num0; i>0; i) { cout << "{" << myArray[num1] << "}" << endl; } I have this for num1 = inputted numbers of the array. Do I need a new array name?

You need to include the 0 in the array, so i >=0 You can keep the same array, just remember 'myArray[num1] doesn't make much sense, since num1 can take any value the user inputs, can be outside the range of indexes of your array, choose the variable your for is sweeping to put inside your array. In this case it's i. You should have something like for(int i = num0; i >= 0; i) { cout << "{" << myArray[i] << "}" << endl; }

Hmmm for some reason, my program keeps crashing... lol I think there's something I'm messing up in the loop! I'll see if I figure it out and then I'll come back to you. Thanks a bunch for your help as always!!! :D
