    it doesnt work.
    What does the code do when you execute it?

    Have you tried writing down on a piece of paper what you want to happen for each element in the three arrays to see how to use the for loop and its index?
    Write one expression on each line showing the array references and the values of the array indexes.

    int add [] = p[i] + q[j];

    What does that line do? Think about it carefully and be very exact.
