Procedural Programming

Procedural Programming


A procedure or function is a self-contained program module that executes a set of specific instructions. The procedural approach focuses on the procedures that must be enacted in order to solve a particular problem. Thus a program can be viewed as a sequence of procedure calls. A procedure calls another (calling procedure) for services. After the sequence of statements in the called procedure is processed, the flow of control continues right after the point where the call was made. A procedure also can call a sub-procedure and in any case, calling procedure and the called procedure are allowed to exchange data in some way. This form of programming has been in existence the longest, and is still in use today by many programmers.
