Procedural Oriented Programming (POP)

In this lesson, you will learn.

• Procedural Oriented Programming (POP)

Procedural Oriented Programming (POP) Language

• Procedural Oriented Programming (POP) is a programming paradigm based on the concept of subroutines or procedure calls also called functions.
• This approach contrasts with Object-Oriented Programming (OOP), which organizes software design around data, or objects, rather than functions and logic.

Key Concepts of POP

Functions and Procedures:

• The core concept of POP is the use of functions or procedures. These are blocks of code that perform a specific task and can be called from other parts of the program.
• A procedure might perform a task and then return control to the calling function, while a function typically returns a value.

Modularity:

• The program is divided into smaller modules or procedures. Each module can be developed and tested independently, which simplifies the programming process and debugging.

Sequential Execution:

• Execution in procedural programming is top-down, starting from the main function or procedure and proceeding through various function calls sequentially.

Variable Scope and Global Variables:

• Variables in procedural programming can be either local to a procedure (local variables) or accessible to all procedures (global variables).
• The use of global variables is common, but it can lead to issues with data integrity and security

Stateful Procedures:

• Procedures in POP can maintain state information through the use of static or global variables. However, unlike OOP, data and methods are not encapsulated together.

Advantages of POP

Simplicity

• Routine tasks and procedural programming can be more straightforward than OOP.

Performance

• In some cases, procedural programs can be more efficient in terms of execution time and memory usage, as there is less overhead than in OOP.

Ease of Learning:

• The concepts of procedural programming are generally easier to grasp for beginners.

Disadvantages

Scalability

• As projects grow in size and complexity, procedural code can become harder to maintain and extend compared to OOP.

Code Reusability

• OOP offers better mechanisms for code reuse through inheritance and polymorphism, which is less inherent in procedural programming.

Data Security

• The widespread use of global variables can lead to issues with data security and integrity.

Maintenance Challenges

• Large procedural programs can become unwieldy, making maintenance and updates challenging.

POP Languages

• C is the most prominent example of a procedural programming language.
• Other examples include Fortran, Pascal, and BASIC.
