[jb2918]

copied word for word from online video instruction and i have this problem all the time it wont run, but theirs always does.

Maybe it is a microsoft visual studio error on my part in setting up the type of application or something? If so please direct me to a solution. I am using microsoft visual studio 2017 community edition

I know it is alot, I am fresh with no experience, trying to learn. code is copied word for word. Works on his end.

here are all the errors:

I mean I understand the lesson at a basic level for what he is trying to explain, and how basic classes work. Just bothers me lesson after lesson not being able to run word for word code.

Your app works fine on VS 2015 CE and on the shell. http://cpp.sh/3yzie
Try to recreate the project. Create an empty folder, save your file as main.cpp and choose File->Project from existing code. Choose Visual C++, the folder, select Console app and hit finish.

It's basically working -- are you sure you didn't change anything? See it in action here https://repl.it/repls/PortlyColorfulResources

The idea behind system("pause"); -- it's a Windows way of making sure the Console that it creates doesn't quickly run and close before you can read it. I changed it to a cin.get();, which should work for multiple platforms. Since you include <iostream> you should have access to the system() command; not sure why you have an error.

The other errors look scarier. Especially make sure you didn't add an extra open bracket or forgot a closing bracket -- if you click to the left or to the right (depending on IDE) of the opening curly brace, does it highlight the corresponding closing brace?

You are awesome! thank you! nothing worse than not being able to move on to another lesson.
