I am currently taking C++ but i am also in Software engineering. for my software engineering class we have to create a project(of our own choosing) coding included by April. my question is how would i use c++ to create a rigorous/simple software.... i want to do something pertaining to restuarants/bakery/something like a automatic coffee machine but its not a coffee machine. i know how to do VBA(visual basic applications) and interfaces.

What do you mean "How do I use c++ to do ..." - it is a language - once you know what you want to do, you have to figure out how to do it within the language. You'd probably want to have a CoffeeMachine class that has functions like "PourCup", "IsEmpty", etc.
