Operators are the basic concept of any programming language, used to build a foundation in programming. Different Types of Operators are: - 1. Arithmetic Operators ( +, -, *, /, % ) 2. Relational Operators ( =, !=, <, >, >=, <= ) 3. Logical Operators (&& AND, || OR, ! NOT ) 4. Assignment Operators (=, +=, -=, *=, /=, %=) 5. Bitwise Operators ( & Bitwise AND, << Left Shift, >> Right Shift, | Bitwise OR ) 6. Miscellaneous Operators ( sizeof, &pointer, *pointer, ? condition ) Difference between & and &&: - && = AND OPERATOR For example, here it is used a, b (a && b) AND: Used to check if both the operands(a,b) are true. & = Bitwise AND For example, ( a & b ) Bitwise AND: Converts the value of both the operands into binary form and performs AND- operation bit by bit.
