C run time library

What exactly is a C Run time library and who puts in the _mainCRTStartup() function into our code and why is it needed?

The C runtime library does two things: it implements the documented functions that you can call from your C program, and it contains support code that is used invisibly by the compiler behind the scenes. _mainCRTStartup is an example of behind-the-scenes support - it is called before your main function is called to do things like parse the command line.
