Procedural programming

Definition

In procedural programming, a program contains several steps. These steps can be complex, and in this case, each step calls a routine also known as procedure, method, sub-routine or function.

It's a downward analysis.

Most of the time, procedures and functions change data in the program.

PROGRAM = ALGORITHMS + DATA

Inconvenience

• If you want to change the behavior of a software you need to change the entire code.
• A new development in a software means that we need to write the entire new code
• Software development could be very long and too expensive
