Procedural programming

Choose and Buy Proxies

Procedural programming is a programming paradigm that relies on the concept of procedure calls, where code is organized into reusable blocks or procedures. These procedures contain a series of computational steps to be carried out. It is one of the fundamental programming paradigms used in computer science and software development.

The History of the Origin of Procedural Programming and the First Mention of It

Procedural programming originated in the early 1950s, with the Fortran language, developed by IBM. Fortran introduced the concept of using procedures, subroutines, and functions to modularize code. It was a significant step forward in making programming more structured and organized.

The 1960s and 1970s saw further evolution of procedural programming, with languages such as ALGOL, COBOL, and Pascal building on these concepts. These languages provided more refined constructs for structuring code and controlling program flow.

Detailed Information about Procedural Programming: Expanding the Topic

Procedural programming is based on the concept of procedure calls. It divides the program into reusable procedures or functions, each of which performs a specific task.

Key Concepts:

  • Procedures/Functions: Blocks of code that can be called by name.
  • Control Structures: Use of loops and conditional statements to guide the execution flow.
  • Parameters and Arguments: Passing data to and from procedures.
  • Local and Global Variables: Controlling the scope and lifetime of variables.
  • Modularity: Separation of concerns through well-defined procedures.

The Internal Structure of Procedural Programming: How Procedural Programming Works

In procedural programming, a program is divided into various procedures that are called sequentially or conditionally. Here’s how it works:

  1. Main Program: The starting point, which calls various procedures.
  2. Procedure Definition: Each procedure is defined with specific tasks.
  3. Procedure Call: Procedures are called by name, possibly with parameters.
  4. Execution Flow: Control structures guide the execution flow between procedures.
  5. Return Values: Procedures may return values to the calling procedure.
  6. Termination: The program ends when the main program’s execution is completed.

Analysis of the Key Features of Procedural Programming

  • Modularity: Code separation into procedures makes it easier to understand and maintain.
  • Reusability: Procedures can be used in multiple parts of a program.
  • Maintainability: Changes in one procedure do not affect others.
  • Efficiency: May offer better performance for certain computational tasks.

Types of Procedural Programming: Use Tables and Lists

Procedural programming can be categorized into:

Structured Programming:

Languages that emphasize clear structure and organization, e.g., C, Pascal.

Modular Programming:

Focus on dividing the program into separate, interchangeable modules, e.g., Modula-2.

Object-oriented Programming (with Procedural Characteristics):

Some OOP languages retain procedural characteristics, e.g., Java, C++.
