QUESTION
I'm pretty green when it comes to the world of C++ programming, but I've recently dove headlong into it and am enjoying the learning process.
I've been curious about the Linux side of things though. Throughout my career, I've mainly used Windows environments, but Linux exposure was still there to some degree.
My question is: Given that we have the Win32 API and visual studio on the Windows side, does there exist a Linux equivalent? By 'Linux Equivalent' I mean an IDE similar to Visual Studio (for that intelli-sense auto-complete goodness) and an API structure similar to Win32? (for KDE/gnome for example) Or given that Linux source code right down to the kernel is readily available, would it be best to look at that, and use function calls in my application appropriate to what I want to do?
I think I might be over-simplifying what would be a very ambitious task, but I'm curious about how things work 'under the hood'. One of the best ways I learn is to do things for myself and see the results. Towards that end, I plan on using Linux in a VM. That way I at least have the option of snapshots and the ability to recover to a said snapshot in a worst-case scenario.

Answered 2021-Apr-22 at 04:40Linux is the kernel, a linux based operating system is much more than that. To interact with linux itself you use system calls, then, on top of that you have the GUI, which can be either X server (the historical choice) or Wayland (the new standard). Both works slightly differently and have different APIs.
It is usually easier to work with a higher level framework, Like GTKmm or Qt if you want to reach the level of functionality in the win32 api. Those a slightly more expensive than win32, as they are abstraction layers on top of the actual graphical server, but the benefit is that they also work on windows (as abstraction on top of win32). I do prefer Qt to be honest, but GTK is a fine choice too (it is a c-library, but there exist a c++ port, GTKmm).
As for the IDE, I use Qt Creator, which is quite good. Other options include KDevelop, Eclipse, Visual studio (which has a linux version), ... and VIM if you are a purist.

QUESTION
I'm currently working on a project for my Computer Organization class, and my professor decided to throw us headlong into a C++ project with no prior class time or experience besides bitwise operators and memory pointers. The goal of the project is to create a program that can compress or decompress files using Run Length Encoding, and we were given a framework of code to work with. I'm currently trying to write the Encode function, and this is what I have so far. Keep in mind, I have absolutely no prior experience in C or C++.
