## mugwump101 4 years ago Write a program that allows a user to input up to 20 integers. First ask the user how many numbers (num), up to 20, they wish to enter. Then prompt the user for num numbers, storing them in an array.

1. Narsat

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.

Yeah I just figured out myself LOL XD

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.

Thanks again :D

5. mugwump101

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

6. Narsat

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]+", "); }

7. Narsat

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

8. mugwump101

Hmmm let me try to work it out.

9. mugwump101

Why did you write array[i]+?

10. Narsat

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)

11. mugwump101

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

12. mugwump101

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?

13. Narsat

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

You're welcome :) good luck
