Hi 
Here’s my code:
#include <iostream> /* load iostream header file into code before moving forward */
int main() /* () pass code into function */

//Print welcome messages to terminal
std::cout << "You are tasked with solving a mathematical puzzle box." ;

const int CodeA = 4;
const int CodeB = 2;
const int CodeC = 1;
/* This is a multi

const int CodeSum = CodeA + CodeB + CodeC;
const int CodeProduct = CodeA * CodeB * CodeC;
// Print sum and product to terminal
std::cout << std::endl;
std::cout << "There are 3 numbers required to solve the puzzle..." << std::endl;

HOWEVER, I’m finding that if I input three numbers that satisfy the product but NOT the sum, I still attain the win-state message. Anyone else care to try it in their code and see if I did something wrong?
*EDIT: Got it! I think the code didn’t auto-save properly or something, no longer giving me the false win-state.

Here’s my code after the if and else lesson. Does this code look alright? I’m finding I’m adding a good deal of “std::cout << std::endl;” to skip lines in the terminal so it looks clean once the code is run. Is there a simpler way to do this?

This is where I’m at right now:
Had my first issue that I had to debug while doing this lesson. Was silly enough to write a semicolon after the if condition. 
Resulted in getting the same message whether I gave the program the correct answer or not. 
My progresso in making game here.
