struct type and Int,char, array and other basic types, is also a C language data type, but this is a custom data type, we can be based on the requirements of various basic data types constructed.

Follow the general rules used by variables when using struct variables. A struct type declaration is generally placed at the very front of the code, which can be used in the entire program file or in a header file.
