C

Although many people, especially those who have a good understanding of software engineering but have not yet reached the bottle, despise the use of c language to re-do it. They highly recommend c ++ and other OO languages, it is believed that there

In C language programming, we will encounter some functions with variable parameter numbers, such as printf ():Int printf (const char * format ,...); In addition to the fixed format parameter, the number and type of parameters that follow are

We develop programs in the Linux environment and have to write Makefile by ourselves. A slightly larger project will contain many. c source files.If we use gcc to compile each source file one by one, the efficiency will be much lower. However, if we

The macro definition uses variable parameters, which makes it much easier to use. For details, refer to the msdn example:   Support for variadic macros was introduced in Visual C ++ 2005. // Variadic_macros.cpp# Include # Define EMPTY # Define CHECK1
