Hello, I am learning the ropes here. I have a non-code question, strictly conceptual. How (generally speaking) do I design my project in Visual Studio C++ to acheive the flow in the block diagram, and specifically how do I access Var A and Var B from Main.cpp if they are all modularly constructed?

1. Main.cpp and programs 1 and 2 should start from a single executable and run by themselves endlessly until terminated

2. Main.cpp has to be able to access Var A and B (which are being constantly recalculated) on the fly.

I want to take advantage of parallel programaming for my project.

Thanks in advance,

M.
