What is procedural or algorithmic programming?
Procedural programming is a programming methodology which divides a task into routines or procedures and process, one by one according to their relevance in task completion. Thus procedural or algorithmic programming is based upon concept of procedure call. Here procedures or subroutines are series of computational steps. It enables the programmers to specify simple interface, very suitable for reusability, and procedures are self-contained. Because of reusability, different people can use the code written by someone. This also paves way to creation of programming libraries.
Procedural programming offers the following advantages:
1. Ease of implementation
2. Easier to keep track of program flow.
3. Modularized
4. Need less memory

Disadvantage of procedural programming can be summed up as:
1. Data is exposed to whole system.
2. Real world object mapping is difficult.
3. New user data type creation is very difficult.

Reusability

Procedural programming does achieve reusability of code within the same program as well as other programs. This is achieved by creating reusable chunk of code called procedures. Procedures can be declared and defined locally or globally inside a program. It enables the programmer to call the specific procedure at any point of the program. But here is a point to notice that local declaration permits reuse only within the local scope while a global declaration facilitates reuse of the code in any part of the program. If the procedures are placed inside a global library, they can be accessed from other programs as well. But unlike object oriented programming approach, inheritance cannot be achieved in procedural programming and thus, only a particular set of attributes cannot be reused. If some procedure has to be reused, it has to be
