    Exclamation problem with a for loop (emergancy)

    This project is due in a few hours (midnight tonight)
    the only remaining problem is that this loop will not execute:

    int x = (size - sizearray - index);
    for (int g = 0; g < x; g++)
    {
    cout << "in the loop" << endl;
    newarray[g + index + sizearray] = temparray[g - sizearray + index];
    cout << newarray[g+index+sizearray] << temparray[g-sizearray+index];
    }
    cout << endl;
    cout << endl;

    please forgive all of the debugging statements.
    the program used dynamic arrays, the function this loop is in inserts an array of given size at a given index bumping the values of the origional array up. this loop is supposed to set the last few values of the array...
    any help would be much appreciated

    int x = (size - sizearray - index);
    what sort of values will be in size, sizearray and index.
    If you end up with a negative number in x your loop will not execute
    All spelling mistakes, syntatical errors and stupid comments are intentional.

    Exclamation i did not think of that, but still, it didnt work

    amazingly i did not think of that, however after rewriting the loop to eliminate the negative possibility it still will not run
    this is the new loop code
    int x = (sizearray + index);
    cout << x << endl;
    for (int y = x; y < size; y++)
    {
    newarray[y] = temparray[y - sizearray];
    }

    to clear things up a little
    sizearray is the size of the array to be inserted
    index is the index at which the array will be inserted
    size is the size of the main array
