What is C?

C is a statically-typed programming language that follows a procedural programming paradigm, where everything is a function or procedure. It supports lexical variable scopes, recursion, and structured programming. Developed by Dennis Ritchie at Bell Labs, C was intended to overcome the challenges of programming languages like B, BASIC, and BPCL. It gained popularity in the 1980s for developing mainframes and computers, ranging from microcomputers to minicomputers.

Why C is a Popular Programming Language

C is a popular programming language for several reasons. Firstly, it follows a structured programming approach, dividing a problem into smaller subproblems making problem-solving easier.

Secondly, C came before the popular programming languages of today and influenced many of their concepts.

Additionally, C’s low-level programming abilities are useful for developing operating systems and compilers, adding to its popularity.

Why Choose C?

There are plenty of reasons for developers and programmers to choose C as their programming language. Here are a few convincing ones:

* C allows for close work with hardware, making it ideal for system programming.
* It has influenced modern programming languages due to being created before them.
* C’s no-frills syntax and necessary features make it faster than other popular programming languages.

C is a popular programming language for these reasons and more. Check out the “Top Features of the C Language” section below for even more reasons to use C.

Top Features of C Language

C Language provides a variety of features which make it a popular choice as a programming language. Some of its key features are:

– Structured programming approach
– Machine-independent build
– Availability of pointers
– Static and dynamic memory allocation
– Bit manipulation operators
– Rich library functions
– Ability to interface with Assembly and low-level code
– Flexibility in memory access and management
– Efficient error control with standard error handling techniques
– Portability across different platforms and operating systems
– Inline function feature for optimization

Vibrant Set of In-built Operators in C Programming Language

// C program to demonstrate various operators
#include <stdio.h>

int main()
int a = 10, b = 4;
float c = 3.5, d = 2.5;

// arithmetic operators
printf("Addition: %d\n", a + b);
printf("Subtraction: %d\n", a - b);
printf("Multiplication: %d\n", a * b);
printf("Division: %d\n", a / b);
printf("Modulus: %d\n", a % b);

// relational operators
printf("Greater than: %d\n", a > b);
printf("Less than: %d\n", a < b); printf("Equal to: %d\n", a == b); printf("Not Equal to: %d\n", a != b); // logical operators printf("Logical AND: %d\n", (a > b) && (c > d));
printf("Logical OR: %d\n", (a > b) || (c < d)); printf("Logical NOT: %d\n", !(a > b));

return 0;

The use of these in-built operators in C programming language makes it easy to perform various operations on variables and helps in writing basic as well as advanced programs.

C is Highly Extensible

C is a well-liked programming language because of its significant extensibility. It allows the extension of existing C programs by appending more code.


Dynamic memory allocation is a key feature of C programming. With this feature, data structure size can be modified during runtime. C provides several prebuilt functions to deal with memory allocation, including free(), calloc(), malloc(), and realloc(). These functions allow for efficient memory management and deallocation.

Fast and Efficient

C programming language offers better performance due to its essential features and static typing, unlike newer programming languages that have more features leading to more processing, hence reducing performance. C’s statically-typed nature entails defining variable data types during declaration, which checks variable types only at compile time and not at runtime. This means that C’s code execution speed is faster than that of interpreter-based languages due to it being a compiler-based programming language.

Modularity in C Programming

Writing code in small, independent and reusable pieces is called modularity in programming. C language offers modularity through functions, libraries and modules. C language also has header files concept which makes it highly modular.

High modularity makes the code reusable, and C language already has a vast range of predefined functions stored in libraries. Some of the famous C libraries include BerkeleyDB, checkedthreads, Cranium, Debug, libsodium, and musl, etc.

C language also allows creating custom libraries, making it a more beginner-friendly program, and saves experienced programmers’ effort. By saving functions as libraries, one can avoid the pain of reinventing the whole code.

Procedural Programming in C

Programming languages have different paradigms; procedural, object-oriented, and functional are a few of them. C follows the procedural programming paradigm, also known as imperative programming, which aims to make computer programs clear, easy to develop, and of good quality.

The advantages of the procedural programming paradigm in C include:

* Easy-to-understand code.
* Simple implementation of algorithms.
* Increased code reusability.
* Linear program flow that simplifies tracking.

In C, instructions are executed step-by-step using functions, as everything in it is a function. C programs are divided into tasks, each of which is completed using a function.

Middle-Level Language

The C programming language is considered a middle-level language since it allows for direct manipulation of computer hardware while also incorporating features of high-level languages. This unique combination makes C a powerful language to use.

Pointers in Programming

Pointers are powerful programming tools that allow for direct interaction with memory locations. They simplify working with functions, arrays, and memory. Dynamic memory allocation is also made possible thanks to pointers. In C, a pointer is a variable that stores the memory address of another variable as its value. Before using a pointer, it must be declared like any other variable.

Portability in C Programming

C programming boasts portability as one of its standout features. This means that a C program developed on one OS can be compiled and executed on any other operating system with minimal machine-specific modifications. This ease of transfer makes it a hardware-agnostic language and saves programmers from having to rewrite code repeatedly to implement their systems across different platforms.

C as a simple and elegant programming language

C is a programming language that follows the traditional approach of breaking down large problems into smaller ones for individual solutions, making it easier to learn and understand. Its no-frills syntax makes it easy for developers to create or rewrite C programs, making it a preferred introductory language in schools and colleges as well as professional programming courses.

Suitable For Various Uses

C is a versatile programming language that can be used for various purposes. It can be used for developing anything from games and photo editing software to compilers and system software. Here are some of the best uses of C:

– Operating systems like Unix and Microsoft Windows are developed using C.
– C works closely with hardware, making it an ideal choice for developing applications and drivers for embedded systems.
– C is also suitable for developing graphical user interfaces, as seen in Adobe Illustrator, Adobe Photoshop, and Adobe Premiere.
– Modern programming languages and platforms such as MATLAB and Wolfram Mathematica are also developed using C.

The Enduring Popularity of C in 2022

Despite its age, C remains one of the top programming languages to learn in 2022. While a sole proficiency in C may not earn you a high-paying job, pairing it with modern tools like Python, JavaScript, MySQL, NodeJS, Nginx, and Apache Server can lead to highly lucrative and satisfying developer positions. As such, it is worth considering learning or strengthening your C skills.


C has numerous advantageous features, including:

  • High portability
  • Efficient execution speed
  • Access to a wide range of libraries, frameworks, and tools
  • Low-level hardware support

What sets C language apart?

C language’s uniqueness stems from its longevity of over five decades while still being relevant, flexibility to operate on multiple platforms, influence from prominent programming languages, and the capability of low-level programming.

// example code

int main() {
printf(“Hello, world!”);
return 0;

What Makes C Programming Language Unique?

C is a versatile language that can be used for both high-level and system programming. Its knowledge can help in learning various other programming languages as several of them are influenced by C language.
