Programming - need help with modules?
Okay so I have to design a program that uses modules that requires me to find the total cost of something... Without getting into specifics, the user is prompted to enter 2 inputs, and I am able to find the cost of labor, as well as the cost of paint in two seperate modules... How can I create a module that adds the result of the costOfLabor module and the costOfPaint module?
Total cost = cost of labor + cost of paint
Sorry, I forgot to add I am just creating a pseudocode program

To modularize that process, I would expect you to create one module for gathering inputs and another for computing costs rather than separate modules for computing each cost.
Modularization is normally done following a function decomposition and it normally produces modules for the functions to be performed... something like increasing a basic cost by a tax amount is the same function, regardless of what' the cost is paying for.
Interacting with a user, on the other hand, is a totally different operation than calculating a cost. If I assign a task like this, dividing the process along functional lines like this is what I'd be looking for. (I'll leave it to you to decide your steps to pseudocode in a module for getting user input or one for totalling cost components -- that should be pretty straightforward.)
