////////////////////////////////////////////////////////////////////////////////////Hey, guys
i'm trying to write a program that basically, lets the user choose from a menu option. The menu is all the way up top. I was going fine till I hit the addSpeaker function. As you can see, i wrote down bunch of if/else and cout/cin statements. I was wondering, isn't there some other shorter way of doing it? like, when you wanna assign some number to something, you can use "for" loop and the program goes through everything and finds that spot and puts that number, and etc. You know what i mean? like, instead of writing bunch of lines of code, isn't there something shorter and simpler?
anybody?
thank you
