correct on all counts, you have correctly identified that the standard makes the code much more easily readable and helps you identify errors. I enforce the standards at our company and I therefore never write without using that standard. The standard we use is essentially an extension of C99 or sometimes called ANSI-C standard and is used heavily in the sector I work, which is embedded programming. Companies in the game market you are looking at tend to use C++ (UNREAL GAME ENGINE etc) or C# (UNITY GAME ENGINE) and there standard may differ slightly as the majority of the code won't be C compliant, and they have other pressures for readability. So generally in large companies you will be expected to write to a standard and there will usually be a process to check code into the active repository. So while learning coding try and have your own standard but just remember you may have to adapt when you are employed. The company is not going to rewrite an entire repository to your standard even if you could argue it was better. So my standard is not the "absolute best" it's just a standard I would generally have to write to at work. In vino veritas

It does offer boundary condition, just use modern C++ constructs (vector, array, string...) instead of their unsafe C equivalent (pointers, char*...) If you are using a modern version of Visual Studio, there are additional checks made by the compiler and runtime to check boundary conditions (Security Features in the CRT[^]) and also they offer a set of safer runtime API (all the _s functions like strcpy_s instead of strcpy) Remember that if the language let you shoot yourself in the foot, there is no excuse try not to by following best practice when coding. I'd rather be phishing!
