Where is the main function located in the program?

The main function must be located after the library function called by the system. The main function, also known as the main function, is the starting point of program execution. Main is relative, just like the overtones of phonetic theory. Overtones are other functions in the program except main, which cater to people's way of thinking. Generative rather than inevitable patterns.

This question is indeed about choosing b. Many people choose c because it is a partial generalization. If c is correct, it should Put it this way: the main function is located anywhere after the library function called by the system, which is correct.

Extended information:

In C language, a program, no matter complex or simple, is generally a "function"; this function is called It is the "main() function", that is, the "main function". For example, if there is a "cooking" program, then the "cooking" process is the "main function". In the main function, depending on the situation, you may also need to call sub-functions such as "buying vegetables, cutting vegetables, cooking vegetables".

The main function must exist in most programs, but there are still exceptions. For example, in Windows programming, you can write a dynamic link library (dll) module, which is code that can be used by other Windows programs. Since the DLL module is not an independent program, there is no need for a main function. As another example, programs used in professional environments—such as control chips in robots—may not require a main function.
