So I recently started following the James M Kernel Dev and was able to create an Operating System in C++ .

Here is the Source on Github : Just Another OS

I have a couple of questions:

1. Is my coding style ok ?
2. It it wrong to have same name for standard Library Functions since I am making my own ?
3. Is it wrong to write bash Scripts for building the project ?
4. Thanks in Advance for Pointing out the flaws in my design :D
