5 Advantages and Disadvantages of Modular Programming | Drawbacks & Benefits of Modular Programming

 

The idea behind modular programming is to break up a huge program into smaller parts that can be given different tasks. These sections of the program are referred to as modules. Consider these modules as a single unit. These modules can all be combined to create the application, which is the overall architecture.

Functions are grouped based on similarities between them. While other functions are preserved as units, identical functions are grouped individually. Reusing the latter with other programs is permitted. Some of the more well-known programming languages, including Java, C++, etc., use modular programming techniques.

The ultimate goal of modular programming is to integrate easily with more complex software systems. For many developers, it is one of the fundamental concepts of programming. They aren't faultless, though. Developers need to be aware of all the benefits and drawbacks of modular programming.

I will be looking at 5 Advantages and Disadvantages of Modular Programming | Drawbacks & Benefits of Modular Programming in this essay. You now have an understanding of the pros and cons of modular programming.


Now let's get started,

Advantages of Modular Programming

1. Simplicity

Programming in modules includes user-defined functions. A distinct duty is allocated to each of these functions. Code that has this kind of functionality is easier to read. The functions must, however, be well described and have a tidy structure.


2. Collaboration

Programming collaboration is made possible by the modular programming idea. A sizable team of developers works together to create the program, as opposed to just one individual. 

 

Each of these developers will be handling distinct aspects of the code, such that a massive project is divided down into smaller components. 

 

The jobs are distributed based on the files, repositories, or functionalities.


3. Code Reusability

A developer may occasionally need to use the same code in several different locations. In this case, modularity has a special benefit that allows for code reuse. 

 

The codes can be added to the desired locations without needing to be copied and pasted. 

 

In addition to reusing the methods and functionality, this eliminates the requirement to write a program from start.


4. Error Identification

In modular programming, each module is divided into multiple sections, each assigned a unique set of codes. Examining the code facilitates testing and debugging of larger programs. 

 

The coder is already aware of the specific section of the code that contains the fault. They don't have to waste time looking through each and every line of code.


5. Task Execution

A major project requires the participation of numerous programmers to be completed. Every module is worked on its own. As a result, the rate at which the programs are created likewise quickens.

Disadvantages of Modular Programming

1. Performance

In general, modular programming uses longer code snippets. Therefore, you must delete dead codes from your dependencies. If not, it can have an impact on the application's performance.


2. Security

Strong security is present in monolithic codes. With these codes, hacking and piratery are nearly difficult. Modular programming does not have these kind of security features.


3. Module Integration

The designers of the modules may adhere to various styles. As a result, adding modules into programs will result in variations in the work.


4. Testing & Debugging

Despite being divided into multiple sections, each module has thousands of lines of code. This makes the process of testing and debugging quite challenging. Put otherwise, it takes a lot of time.


5. Memory Consumption

Programming in modules uses a significant amount of memory. This is as a result of some modules having duplicate jobs.
