Well, first off, when using the #define preproccessor in C++, can I keep it empty and fill it in later for an if-else statement block? Or do I have to fill them in right after declaring them?


Also, how would I set up my functions to do a math problem untill a certain result, printing the result given for each time it does the equation, untill it reaches that certain result, and then wait for the user to press a key before continuing?
