Advantages and Disadvantages of C Programming – Discover the Secrets of C

C is one of the oldest languages that cannot be replaced by any other language, as it is the core of every machine. In the 21st century, where languages like Java, Python are reigning the market, you should not worry about how relevant the C programming language is and if you are still not sure, proceed with this tutorial “Advantages and Disadvantages of C ” to know how powerful C language is. Well, everything has its qualities and limitations that make it unique.

“Don’t judge a book by its cover.”

So, let’s begin our discussion on the advantages and disadvantages of C.

Advantages and Disadvantages of C

Advantages and Disadvantages of C language

First of all, let us discuss what makes C language as the mother of all languages. There are various benefits of C programming that depends on these positive points which can surely define the functionality of C in a better manner.

1. Advantages of C Programming Language

1.1. Building block for many programming languages

C is considered to be the most fundamental language that needs to be studied if you are beginning with any programming language. Many programming languages such as Python, C++, Java, etc. are built with the base of C language.

1.2. Powerful and efficient language

C is a strong language as it contains many datatypes and operators to give you a vast platform to perform all kinds of operations.

1.3. Portable language

C is very flexible, or we can say machine independent language that helps you to run your code on any machine without making any change of just a few changes in the code.

1.4. Built-in functions

There are only 32 keywords in ANSI C, having many built-in functions. These functions are helpful when building a program in C.

1.5. Quality to extend itself

Another crucial ability of C is to extend itself. As we have already studied that C language has its own set of functions in the C library. So, it becomes easy to use those functions. We can add our function to the library and make code simpler.

1.6. Structured programming language

C is structured-based functioning. It means the issues or complex problems are divided into smaller blocks or functions. Then, it will solve your issues. This modular structure helps in easier and simpler testing and maintenance.

1.7. Middle-level language

C is a middle-level programming language that means it supports high-level programming as well as a low-level programming language. It supports the use of kernels and drivers in low-level programming and also supports system software applications in the high-level programming language.

1.8. Implementation of algorithms and data structures

The Use of algorithms and data structures in C has made program computations very fast and smooth. Thus, C language can be used in complex calculations and operations such as MATLAB.

1.9. Procedural programming language

C follows a proper procedure for its functions, subroutine. As it uses procedural programming, it becomes easier for C to identify code structure and to solve any problem in a specific series of code. In procedural C variables and functions are declared before use.

1.10. Dynamic memory allocation

C provides dynamic memory allocation that means you are free to allocate memory at run time. For example, if you don’t know how much memory is required, you can still run a program in C and assign the memory at the same time.

1.11. System-programming

C follows a system based programming system that means the programming is done for the hardware devices.

So, with this, we are aware of why C considered as a very powerful language. Why was it important to know the advantages of C?

When we study anything new, it becomes important to know the benefits that we gain from that technology. This allows us to grow our interest and implement our learnings in a practical scenario. Now, moving to our next part of the “Advantages and Disadvantages of C Programming Language”.

2. Disadvantages of C Programming language

As we have already discussed the advantages of C. You might have understood when we write a program in C; it becomes really easy to understand the code with the combination of all the above advantages.

You might be thinking that why we are not approaching the language practically and studying the theoretical part in every tutorial. It is because if you will understand the basic functionalities of the language and the methods or operation of the programming language it becomes easy for you to know whether this language is suitable with your choice of career or not.

Also, with all the basic knowledge of the language, you can understand the flow of any program.

So, now let us see what the limitations of C programming language are-

1. Concept of OOPs

C is a very vast language, but still, it is not using the concept of OOPs (inheritance, polymorphism, encapsulation) in it. C follows the procedural programming approach.

2. Run-time checking

In C language the errors or the bugs do not get detected after each line of code. Instead, the compiler shows all the errors after writing the program. It makes the checking of code very complex in large programs.

3. Concept of namespace

C does not implement the concept of a namespace in it. A namespace is structured as a chain of commands to allow the reuse of names in different contexts. And, without namespace, we cannot declare two variables of the same name.

But, C programming lacks in this feature, and hence you cannot define a variable with the same name in C.

4. Lack of Exception Handling

Exception Handling is one of the most important features of programming languages. While compiling the code, various anomalies and bugs can occur. Exception Handling allows you to catch the error and take appropriate responses. However, C does not exhibit this important feature.

5. Constructor or destructor

C does not have any constructor or destructor in it.

As constructor & destructor is basic functionality of Object Oriented Programming, and it is a member function created as soon as an object of the class is created. You will be studying constructor and destructor in detail later.

6. Low level of abstraction

C is a small and core machine language that has minimum data hiding and exclusive visibility that affects the security of this language.


Here, we end our tutorial ‘Advantages and Disadvantages of C Programming’. Hope all of our creative brains got the purpose of this tutorial and with this simple understanding of the pros and cons of C, you might have understood how powerful C is in its process of implementation and execution and at the same time how it lacks behind other languages in some aspects.

    Why do you consider lack of OOP a disadvantage? It is just a bloated wrapper around simple logic that adds meaningless complexity

      Hello Jim,
      Thanks for connecting DataFlair. We consider OOP as disadvantages of C because implementing the concepts of OOP undoubtedly makes your program not as simple as it could have been for the programmer, but it is an inevitable fact that without OOP, you are missing out on a lot of features offered by other programming languages like C++ and Java.
      For instance, consider a situation where you are working in a bank, and you wish to enter the details of employees of a particular department. You solve this problem by using classes, a data structure implementing the feature available in OOP-inheritance. You wouldn’t prefer giving out the details of the salary of the employees to some other class. The choice of access specifiers helps you solve this problem.
      Hope, it helps!
