Q.Write the features of C.

C is a general-purpose, middle-level language valued for its structured design, portability, rich library and efficiency.

[!ANSWER]

Key features of C are: it is a middle-level, structured (modular) language; it is portable across machines; it has a rich set of built-in library functions and powerful operators; it supports pointers, recursion and dynamic memory; and it produces fast, efficient and extensible code.

[!TLDR]

C is a middle-level, structured, portable and efficient language with a rich library, powerful operators and pointer support.

C combines the features of high-level and low-level languages, which is why it is used for both system and application programming. Its main features are:

1. Middle-level language - it supports high-level constructs as well as low-level bit and memory operations.
2. Structured / modular - a program is broken into functions, making it easy to write, test and maintain.
3. Portable - a C program written on one machine can be run on another with little or no change.
4. Rich library - a large collection of built-in functions (in headers such as stdio.h, math.h) speeds up development.
5. Powerful operators - a wide range of arithmetic, relational, logical and bitwise operators.
6. Fast and efficient - compiled code runs quickly and uses memory economically.
7. Extensible - new functions can be added to the library, and programs can be extended easily.
8. Supports pointers, recursion and dynamic memory allocation, giving close control over the hardware.

[!ANSWER]

C is middle-level, structured/modular, portable, efficient and extensible, with a rich library, powerful operators, and support for pointers, recursion and dynamic memory.
