C Introduction
- What is C?
- C is a general-purpose programming language.
- It was created by Dennis Ritchie in 1972 at Bell Laboratories (AT&T, USA).
- C is used to write system software, applications, and operating systems.
- Why is C still popular?
- Even though it’s old, it’s still very popular because:
- It is fast and efficient.
- It is the base for many modern languages like C++, Java, Python, etc.
- It helps to understand computer working (like memory, logic, hardware).
- It is used in embedded systems and operating systems.
- Relation with UNIX
- C language was developed to create the UNIX operating system.
- That’s why C is strongly connected with UNIX.
- Many parts of UNIX are written in C.
- Features of C Language
- Simple and powerful
- Portable (works on any computer)
- Structured language
- Rich set of built-in functions
- Supports pointers and direct memory access
- Fast execution
Why Learn C?
- C is Very Popular
- C is one of the most popular programming languages in the world.
- It is used in schools, colleges, and industries to teach programming basics.
- Easy to Learn Other Languages
- If you learn C, you can easily learn other languages like
👉 Java, Python, C++, and C#.
Reason: These languages have similar syntax and logic as C.
- Understand Computer Memory
- C helps you understand how computer memory works.
- Very Fast Execution
- C programs run very fast compared to languages like Java or Python.
- This is because C is closer to machine-level code.
- Versatile Language
- C is a versatile (multi-use) language.
- It can be used to build:
- Applications
- Operating systems
- Game engines
- Embedded systems
- Compilers
