compiler compiles a program, it compiles only one source file and generates the corresponding intermediate file (for the VC, the. obj file), and then the connector unifies all intermediate files to form an executable file. The problem is that when

The Declaration tells the compiler some information to assist the compiler in syntax analysis and avoid compiler errors. The definition is to tell the compiler to generate some code that will be used by the connector. That is, the Declaration is for

When there is too much code in your code, it is especially inconvenient to read the code, and you need to use a newline character "\". Be aware of two points when using line breaks: The 1.c compiler is based on ";" To determine if it is a statement,
