Static C language The C language program can be seen as a series of external objects, which may be variables or functions. The internal variable refers to the function parameters and variables defined within the function. External variables are defined outside of functions, so they can be used in many functions. Because the C language does not allow other functions to be defined in one function, the function itself can only be "external."Because the C

Internal variables refer to the function parameters and variables defined within the function. External variables are defined outside functions, so they can be used in many functions. Since the C language does not allow defining other functions in a function, the function itself can only be "external ".C language code is organized in files. In all source files of a source program,
