Introduction To C Programming language
What is C?
C programming language is a procedural and general purpose high level programming language. C programming language is a powerful and widely used programming language and it is mostly known for its flexibility, efficiency and low-level programming capability. C has had a profound influence on many other programming languages and is considered the foundation for modern operating systems like Linux.
Following are the key features of C-Programming language:
- Syntax:
- C has a relatively simple and concise syntax, making it easy to learn and read.Programs in C consist of functions, and each function contains statements that define the actions to be performed.
- Procedural Programming:
- C is a procedural programming language, meaning it follows a top-down approach, breaking down a program into functions.
- It emphasizes functions and structured programming, making it suitable for developing modular and maintainable code.
- Low-Level Features:
- C provides direct access to memory, allowing for efficient manipulation of hardware and system resources.
- Features like pointers make it possible to work with memory addresses directly, which can be powerful but requires careful management to avoid errors.
- Portability:
- C is highly portable, meaning programs written in C can run on different platforms with minimal or no modification.
- This is facilitated by the use of a compiler, which translates C code into machine code for a specific platform.
- Standard Libraries:
- C comes with a set of standard libraries that provide a wide range of functions for tasks like input/output, string manipulation, memory allocation, and more.
- These libraries enhance the functionality of C and simplify common programming tasks.
- Efficiency:
- C is known for its high performance and efficiency. It allows for close control over system resources and is often used for developing performance-critical applications and system software.
- Influence on Other Languages:
- Many modern programming languages, such as C++, C#, and Objective-C, have been influenced by C and share similar syntax or concepts.
- Community and Legacy:
- C has a large and active community of developers. Its long-standing legacy ensures a wealth of resources, documentation, and third-party libraries.
