Entry point

Entry point is the point in a program where the execution of a program begins, and where the program

has access to command line arguments. Entry points are actually defined by the operating system or

the hardware context from which a program is meant to be executed. This is the reason why

programmers must follow conventions as to how they write functions. For example in $C$ or $C++,$ any

program must contain a function int main$()$ as that is first executed when the program begins.

Your task is to write a small treatise on entry points that introduce this matter to programmers not

familiar with the inner workings of operating systems. However, ensure you do not oversimplify

anything: expand upon

What is an entry point and how they work $($the paragraph above is not detailed enough$)$

Why an entry point is necessary, and why this role has to be played by the operating system

On Windows, the entry point of a standard Windows executable is int WinMain$($HINSTANCE hInstance,

HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd$)$;$.$ Explain these arguments, and the origin

of WinMain$()$ as an entrypoint.
