In this C Tutorial, you’ll learn all C programming basic to advanced concepts like variables, arrays, pointers, strings, loops, etc. This C Programming Tutorial is designed for both beginners as well as experienced professionals, who’re looking to learn and enhance their knowledge of the C programming language.
What is C?
C is a general-purpose, procedural, high-level programming language used in the development of computer software and applications, system programming, games, web development, and more. C language was developed by Dennis M. Ritchie at the Bell Telephone Laboratories in 1972. It is a powerful and flexible language which was first developed for the programming of the UNIX operating System. C is one of the most widely used programming language.
C programming language is known for its simplicity and efficiency. It is the best choice to start with programming as it gives you a foundational understanding of programming.

Why Learn C?
C programming language is one of the most popular programming language. It is a must learn for software engineering students. C is called the mother of all modern programming languages so learning C will help you to learn other languages easily like Java, C++, C#, Python, etc. C language is faster than other programming languages like Java and Python. It can handle low-level programming and we can compile the C code in a variety of computer platforms.
List of some key advantages of C language:
- Easy to learn.
- Versatile Language, which can be used in both applications and technologies.
- Mid-Level Programming Language.
- Structured Programming Language.
Features of C Language
There are some key features of C language that show the ability and power of C language:
- Simplicity and Efficiency: The simple syntax and structured approach make the C language easy to learn.
- Fast Speed: C is one of the fastest programming language because C is a static programming language, which is faster than dynamic languages like Java and Python. C is also a compiler-based which is the reason for faster code compilation and execution.
- Portable: C provides the feature that you write code once and run it anywhere on any computer. It shows the machine-independent nature of the C language.
- Memory Management: C provides lower level memory management using pointers and functions like realloc(), free(), etc.
- Pointers: C comes with pointers. Through pointers, we can directly access or interact with the memory. We can initialize a pointer as an array, variables, etc.
- Structured Language: C provides the features of structural programming that allows you to code into different parts using functions which can be stored as libraries for reusability.
Applications of C Language
C was used in programs that were used in making operating systems. C was known as a system development language because the code written in C runs as fast as the code written in assembly language.
The use of C is given below:
- Operating Systems
- Language Compilers
- Text Editors
- Print Spoolers
- Network Drivers
- Modern Programs
- Language Interpreters
FAQs on C Language
Q1. How to learn C easily?
The first steps towards learning C or any language are to write a hello world program. It gives the understanding of how to write and execute a code. After this, learn the following:
- Loops and Errors
- Arrays and Strings
- Pointers and Memory
Q2. Difference between C and C++?
- C is a procedural programming language.
- It does not support Function overloading.
- Operator overloading is not supported.
- C does not support data hiding which leads to security concerns.
- C++ is both a procedural and object-oriented programming language.
- It supports function overloading.
- Operator overloading is supported.
- Data hiding is supported in C++ by Data Encapsulation.
Q3. Is C easy to learn for beginners?
While C is one of the easy languages, it is still a good first language choice to start with because almost all programming languages are implemented in it. It means that once you learn C language, it’ll be easy to learn more languages like C++, Java, and C#.
