2 Compiling a C program
This chapter describes how to compile C programs using
Programs can be compiled from a single source file or from multiple
source files, and may use system libraries and header files.
Compilation refers to the process of converting a program from the
textual source code, in a programming language such as C or C++,
into machine code, the sequence of 1's and 0's used to control the
central processing unit (CPU) of the computer. This machine code is then
stored in a file known as an executable file, sometimes referred
to as a binary file.
