C# or C++

C++ Is made for hacking, C# Requires a lot more libraries. I would recommend going into C++ if you want to make hacks / game mods, but if you want to make front end applications (eg. Calculator, Web Scrapers, ETC) use C#.

C++ Is much better at desktop applications, hacks, etc
C# is more proficient at Web Based Applications, Minor Desktop Applications, etc (It's a lot quicker to code in)

So really, it's what you want to use it for.

In my opinion I would say learn C++ first as you will get experienced in correct layout, correct syntax, and learn good coding practises as its a bigger leap, then after you learn C++ you will have a much easier time learning C# as you have the layout, syntax and coding practises already.

(Keyword for C++, is if it gets hard for you, learn to break the program down into simple classes (Calculator for example, if you can't think of it in the big picture, think of it in the different processes, such as add, Multiply, division, etc. This is a great way to start off with a complex language)

C# will teach you bad habits, do c++ (learn in college or tech school) Try to avoid tutorials online they are mostly written by students and leave out key things you would want to know not to mention when you get stuck your just stuck there isnt anyone to help you.. I am making my first game this semester in college school is best place to learn this sort of thing, if you half ass it and use online tuts your gonna produce sloppy half ass code as a result

This is not always necessary, You're judging this based on many things... I do agree with most online tuts being sloppy, but that doesn't rule out online altogether. Download .PDF files of books that people have written and learn from that. They explain everything in detail so you shouldn't get lost (This is still a method of using online).

He just mentioned Online Tuts, which is true.
Besides, learning at university/school is always better no matter what you wanna do for living.
