Just started learning C++ and I'm not so l337 at programming.
Anyways, by the end of my studies I will make a version 2 which will be a full blown calculator, or way better than this.
I plan on letting the user input how many numbers they would like to do math with, have a number selection instead of an operator selection for ease, (I could do that now) storing some of the variables in a enum and writing a switch statement for the inputs, and some other nerdy stuff that I either couldn't / didn't want to do the first go around.
Anywho, I am just posting this so that if you are starting in C++ you can look at this and ponder.
God this program is rough haha:
- Code: Select all
#include <iostream>
#include <string>
/*All of the functions (a, b, c, d, e, and f) are aligned on the far left of the page by theirself for easy identification
