Operators in C are symbols that tell the compiler to perform specific mathematical, relational, or logical operations. Operators are essential components of expressions and they act on operands (variables or values) to produce a result.
C Arithmetic Operators
An arithmetic operator performs mathematical operations such as addition, subtraction, multiplication, division etc on numerical values (constants and variables).
C Increment and Decrement Operators
C programming has two operators increment ++ and decrement — to change the value of an operand (constant or variable) by 1.
Increment ++ increases the value by 1 whereas decrement — decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand.
C Relational Operators
A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0.
Relational operators are used in decision making and loops.
C Logical Operators
An expression containing logical operator returns either 0 or 1 depending upon whether expression results true or false. Logical operators are commonly used in decision making in C programming.
C Bitwise Operators
During computation, mathematical operations like: addition, subtraction, multiplication, division, etc are converted to bit-level which makes processing faster and saves power.
Bitwise operators are used in C programming to perform bit-level operations.
C Assignment Operators
An assignment operator is used for assigning a value to a variable. The most common assignment operator is =
