Operators

C supports a rich set of operators, which are symbols used within expressions to specify the manipulations to be performed. C has various types of operators:

1. Arithmetic operators: +, -, *, /, %

2. Assignment operator: =

3. Augmented assignment operators: +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=

4. Bitwise logic operators: ~, &, |

5. Bitwise shift operators: <<, >>

6. Boolean logic operators: !, &&, ||

7. Conditional evaluation: ? :

8. Equality testing: ==, !=

9. Function calling: ( )

10. Increment and decrement: ++, --

11. Member selection: ., ->

12. Object size: sizeof

13. Order relations: <, <=, >, >=

14. Reference and dereference: &, *, [ ]

15. Sequencing: ,

16. Subexpression grouping: ( )

17. Type conversion: (typename)

Salient Features of C

C language has some characteristics that define the language and have led to its popularity as a programming language:

• Small size.

• Extensive use of function calls.

• Structured language.

• Low-level (Bitwise) programming is readily available.

• Pointer implementation is used extensively for memory, arrays, structures, and functions.

• It has high-level constructs.

• It can handle low-level activities.

• It produces efficient programs.

• It can be compiled on a variety of computers.
