C – Program Structure
- A C – Program consists of variables and functions which are either internal or external.
- C - Programs generally consist of many small functions rather than a few big ones.
- Communication between the functions is by arguments, values returned by the functions, and through external variables.
- A program may be divided into one or more source files.
- Source files may be compiled separately and linked together, along with previously compiled functions from libraries to form a final program.
