C Programming :
Executing a program written in C involves a series of
steps. These are:
1.
Creating the
program
2.
Compiling the
program
3.
Linking the
program with functions that are needed from the C library4. Executing the program.
Illustrates the process of creating, compiling and executing a C program.
Although these steps remain the same irrespective of the operating
system, system commands for implementing the steps and conventions for
namingfi/es may differ on different systems.
An
operating system is a program that controls the entire operation of a computer
system. All input/out operations are channeled through the operating
system. The operating system, which is an interface between the hardware and
the user, handles the execution of user programs.
The two most popular operating
systems today are UNIX (for minicomputers) and MS-DOS (for microcomputers). We shall discuss briefly the
procedure to be followed in executing C program, under both these
operating systems in the following sections.
