i know that this is a simple code but i'm having problems with it. Problem to be solved

Get two sets of 10 integers from the user and store each set in a separate array. Find the set representing the intersection of the two sets entered and store the intersection in a third array. Then print out the set representing the intersection.

As a minimum you must have separate functions to accomplish each of the following:

- One function to input an array of 10 integers.

- One function to find the intersection of two arrays.

- One function to print the contents of the intersection array.

What problem are you having? You need to post the code you have tried. If you have not started yet, why not? Do the program in small steps -- do the first part first. When that is finished and tested, then move on to the second part.

please post ur code with it . its not possible for me to write the whole program. but I can figure out mistakes in your program.

ok here is my code it runs perfect but it is too complex still to turn in is there anything simpler that i can do?
