What year was the C programming language developed and by whom?
The C programming language was developed in 1972 by Dennis Ritchie and Ken Thompson.
Why is C considered a procedural and structured programming language?
Why is C considered a procedural and structured programming language?
C is considered procedural because it consists of a series of instructions for solving problems, and structured as it allows modular expression through function calls.

Study Notes
C Programming Language Features
- Developed in 1972 by Dennis Ritchie and Ken Thompson primarily for re-implementing the Unix kernel.
- Remains popular due to its low-level memory access, portability, and cross-platform nature.
- Many other programming languages incorporate its features.
- Serves as a foundational language influencing various application areas.
Procedural and Structured Language
- Procedure-oriented and structured; a C program's logic is a sequence of instructions that solve a problem.
- Allows modularity through function calls.
- Often used as an introductory programming language due to its structured approach.
General-Purpose Language
- Designed for diverse applications, from system programming to photo editing software.
- Used extensively in operating systems, databases, and device drivers.
Fast Programming Language
- Compiler-based, leading to faster compilation and execution compared to interpreter-based languages.
- Statically typed, improving speed compared to dynamically typed languages.
- Translates source code directly into machine code, optimizing CPU execution.
Portable Language
- Machine-independent; code can be compiled and run on different machines with minimal or no modifications.
- Promotes code reusability across multiple platforms.
Extensible Language
- Allows adding new features and functionalities to existing C programs through modifications.
- Facilitates expansion and customization of existing code.
Standard Libraries
- Includes extensive libraries with built-in functions for various tasks (OS utilities, string manipulation, mathematical functions).
- Allows programmers to create and integrate user-defined functions into existing libraries.
Pointers
- Enables direct manipulation of computer memory.
- Pointers point to memory locations, facilitating interactions with external hardware and interrupts.
Mid-Level Language
- Offers both low-level memory access and high-level features (keywords, identifiers, modularity).
- Provides a balance by offering direct hardware manipulation unavailable in high-level languages.
Rich Set of Built-in Operators
- Possesses numerous operators for different programming tasks, including complex and concise applications.
- Includes arithmetic, comparison, binary, and pointer-related operators.
Recursion
- Enables functions to call themselves repeatedly until a certain condition is met.
- Facilitates code reusability and backtracking capabilities.
User-Defined Data Types
- Supports fundamental data types (int, float, char) and user-defined data types (structures, unions, enumerations).
- Enhances flexibility and power in defining custom data representations.
Preprocessor Directives
- Includes directives like #include and #define, vital for including external functions, defining macros, and expanding code.
File Handling
- Uses high-level I/O to handle file operations.
- Standard I/O streams (stdin, stdout, stderr) manage input, output, and error handling, enabling file read/write operations.
