- 1. What is C Language? C is a general-purpose programming language. It is known for its efficiency, flexibility, and its role in the development of operating systems, embedded systems, and other software. by palak
- 2. History and Development of C Language 1 Origins C emerged in the early 1970s at Bell Labs, developed by Dennis Ritchie. It evolved from the B programming language, designed to be portable and efficient. 2 Standardization The American National Standards Institute (ANSI) standardized C in 1989, leading to the widespread adoption of the language. 3 Modern Evolution C continues to be developed and maintained, with ongoing updates and revisions to address new technologies and programming paradigms.
- 3. Features and Characteristics of C Language 1 Low-Level Access C provides direct access to hardware and memory, making it suitable for system- level programming. 2 Efficiency C code compiles into highly optimized machine instructions, resulting in fast and efficient execution. 3 Portability C code can be compiled and run on various platforms with minimal changes, thanks to its standard libraries and compiler support. 4 Procedural Programming C supports structured programming concepts, allowing for modular code organization and clear logic flow.
- 4. Data Types and Variables in C Data Type Description int Integer values, representing whole numbers. float Single-precision floating-point numbers, representing real numbers with decimal points. char Characters, representing single letters, digits, or symbols. double Double-precision floating-point numbers, offering more precision than float.
- 5. Operators and Expressions in C Arithmetic Operators These include +, -, *, /, and % for performing mathematical operations. Relational Operators These include ==, !=, >, <, >=, and <= for comparing values. Logical Operators These include && (AND), || (OR), and ! (NOT) for combining conditions.
- 6. Control Structures in C 1 if-else Executes a block of code based on a condition. 2 for Iterates a block of code a specified number of times. 3 while Executes a block of code as long as a condition is true. 4 do-while Executes a block of code at least once, then continues as long as a condition is true.
- 7. Functions and Pointers in C Functions Functions are reusable blocks of code that perform specific tasks, making code modular and easier to maintain. Pointers Pointers store memory addresses and allow direct access to data, enabling efficient memory management and dynamic allocation.
- 8. Applications and Use Cases of C Language Operating Systems C is widely used in the development of operating systems, including Linux, Unix, and Windows. Embedded Systems C is crucial for programming embedded systems, such as microcontrollers, sensors, and other devices with limited resources. Game Development C is used in game engines and libraries for performance-critical tasks, especially in low-level graphics and physics. Scientific Computing C is popular in scientific computing due to its efficiency and its ability to work with complex algorithms and data structures.
