Code-blocks is a free and open-source IDE that can also be built with source code by ourselves. It has support for various compilers like msvc c++, gnu GCC, fortran, embedded compilers, and many with good debugger. It supports all operating systems. It has wxwidgets GUI inbuilt support and doc creators like docoxygen.

The best and the only reason I used CodeBlocks is because it allows the installation of CS50 library which no other application IDE allows. It provides great options to include and make changes to your environment, add custom libraries and make suggestions based on those libraries for the code you're writing. This feature wasn't seen on any other IDEs I have used.

It is very compact and easy to use IDE, especially for C programmers. I am using that IDE for C programming, and it is very user-friendly, thanks to its basic GUI. While using an IDE, the programmers need an excellent environment to write the code and compile it. Code::Blocks gives the users flexibility to adjust compilation parameters or the compiler type etc. Besides, it announces the last release or news about the used compiler. That gives rights to users of being updated. On the other hand, it provides a good debug environment by adjusting the coder's own configurations. The users can customize the IDE by adding different plugins.
