Quote:

All C++ programs must have a main function. If you try to compile a C++ .exe project without a main function, the compiler will raise an error. (Dynamic-link libraries and static libraries don't have a main function.) The main function is where your source code begins execution, but before a program enters the main function, all static class members without explicit initializers are set to zero. In Microsoft C++, global static objects are also initialized before entry to main. Several restrictions apply to the main function that do not apply to any other C++ functions. The main function:

* Cannot be overloaded (see Function Overloading).
* Cannot be declared as inline.
* Cannot be declared as static.
* Cannot have its address taken.
* Cannot be called.
