When you do

while   (Num != Quit);

Do you actually meant:

while (Num != Quit)
{
  // Code here...
}


Hint #1 You need to add braces for the while loop... (and remove the semi-column)
Hint #2 You need to use a different subscript (other that systematically 0
        for storing into Array.


Have a look at the line

while   (Num != Quit);

also think about what

Array [0] = Num;

is going to be doing in a loop

what do you think the next output/action is going to be after

cout <<"Array is full"

indenting, parentheses etc need to be cleaned up to make this do what you want.


  1. While will loop will only execute 1 time.
  2. You will overwrite the first value of the array each time you execute the loop.
