1 Procedural Programming
Disadvantages of procedural programming languages
Procedural programming languages can be advantageous, but it’s important to be aware of any potential drawbacks:
Advantages of procedural programming languages
You can decide if procedural programming is the right paradigm for your next project by considering its advantages:
Top-down approach
Design and creation in procedural programming are based on a top-down method. This method involves defining the program’s main objective before evaluating the parts needed to achieve it.
They might decide to divide some elements of the bigger goal even more into smaller modules. The developer can then start building their modules to create the necessary code to run their program from there.

What are the advantages of disclosing personal information online? What is the system availability requirement? Does the project have high development, operating, or maintenance costs? What are you most proud of in regards to the initial development and ongoing use of the language?
The most valuable role in EVERY group, company, organization, and department is defining, designing, creating, and implementing a process to address a problem or achieve an objective.
There should be a process unless it is a one-time, one-use project. That process needs to be created by someone with a complex enough perspective to ask the right questions, regardless of whether it is managed and implemented by humans, AI, or a combination of the two. Someone who is able to step back, ask the appropriate questions, and state, “What are we really trying to accomplish here? Is there another way to look at it?”
Regardless of whether they hold the title of entrepreneur, manager, consultant, (Vice-)President, CxO, etc., this Self-Assessment equips people to do just that. – they are the people who rule the future. They are the one who will ask the pertinent questions to improve investments in procedural programming.

What Is Procedural Programming ?
Another name for the procedural programming paradigm is “procedure-oriented programming.” The procedure is a key element of this paradigm.
The program code is divided into groups of smaller programs called functions in procedural programming. Each function executes a particular action in accordance with the logic of the program.
As implied by the name, procedural programming organizes the program code into procedures. These procedures are also called as subroutines or functions.
The function has access to and control over both its own local data and shared global data with other functions.
The function becomes the most crucial part of the program in procedural programming, and the functions have unrestricted access to the global data.
Each procedure or subroutine is made up of a group of program statements that carry out a single task. The program can have numerous procedures, and the code for the program can call each procedure numerous times.
A programming paradigm (program organization style) known as procedural programming allows for the organization of a program as a set of functions.
The program code allows for multiple calls to any function to complete the same task as needed.
According to this paradigm, program statements are grouped according to their functionality. According to language syntax, this group of statements can be appropriately referred to as “function.”
For instance, we can group program statements that ask the user for two numbers, add the numbers, and then return the result value.
The procedural program code is written as a list of functions or procedures called subroutines.
The procedures may be defined either within the main program code or externally into a separate header file.
The subroutines can also be defined in a separate file that can be included in the main program as a header file in order to increase the readability of the code.
When a program gets too big, procedural programming divides the code into a number of smaller programs called procedures or subroutines.
Each subroutine performs a specific task. For instance, a programmer could create a subroutine to add or subtract multiple numbers.
According to the program logic, a subroutine or procedure can be written to carry out repetitive tasks in the program code. This helps to eliminate the repetition of code.
The code for a procedural program that has been organized well is much simpler to read and debug. Such code is also easier to maintain.
In procedural programming, the program code is created sequentially using a top-down methodology.
The procedural programming paradigm has some important features . These characteristics specify the program’s structure, its execution order, and the variables’ range.
The program’s execution sequence is determined by the top-down approach. This method starts the program execution at the top and executes the program statements one at a time.
The programmer, however, has a variety of options to alter the order in which the program is executed by using program flow control statements.
In procedural programming, the header files provide a practical way to organize the program code. The program’s top section contains declarations for the header file inclusion statements.
The header files can contain predefined library functions . For example , in C language programming, the Stdio. The standard function declarations for frequently used input and output functions are contained in h (Header File) files.
The header file may also include a library of defined functions that are commonly used in software projects.
Most procedural programming language offer extensive library of predefined functions. These library functions are accessible and simple to incorporate into programs.
Simply put, the programmer can now create all the functions necessary for the desired functionality. And so, in order to shorten the overall development period, predefined library functions are utilized.
Every procedural programming language provides the option for programmers to create user-defined functions. In the program code, the user can define these functions to handle the desired functionality.
Programmers can build libraries of functions that are frequently used in software development projects.
In the program code, the function call statement’s function call statement’s parameters are the placeholders that hold the values passed to the function.
The list of parameters that must be sent to the function is defined in the function declaration. The function’s functionality determines the number of parameters and their data type.
The number of parameters, their order, and the data type of the arguments (passed values) are defined in the function prototype statement and the function declaration.
Procedural Language Pros and Cons
The procedural programming paradigm is easy to understand and use, making it a great way to approach general programming tasks that don’t call for a lot of reusable code or real-world objects. However, a lot of the apps you create don’t work well with procedural programming, so it’s important to understand why so you can approach each problem correctly.
Procedural programming has some advantages. Due to its straightforward structure, it is easy to use, doesn’t require nearly as much memory as other programming paradigms, and works well with interpreters and compilers. However, procedural languages emphasize operation over data, which can be problematic in some situations. They also don’t protect data nearly as well as other language types. The biggest issue with procedural languages may be when an error occurs; in that case, prepare to go through each line of code until you identify the offender.
