WebOperators in C++ can be classified into 6 types: Arithmetic Operators Assignment Operators Relational Operators Logical Operators Bitwise Operators Other Operators 1. C++ Arithmetic Operators Arithmetic operators are used to perform arithmetic operations on variables and data. For example, a + b; WebActually, in C, C++ and other major programming languages the & operator do AND operations in each bit for integral types. The nth bit in a bitwise AND is equal to 1 if and only if the nth bit of both operands are equal to 1. For example:

WebBitwise operators are used to change individual bits in an operand. In C++, bitwise operators perform operations on integer data at the individual bit-level. These operations include testing, setting, or shifting the actual bits. It can be used as a boolean variable that can hold one of two values: True or False. WebExplanation The logic operator expressions have the form 1) Logical NOT 2) Logical AND 3) Logical inclusive OR If the operand is not bool, it is converted to bool using contextual conversion to bool: it is only well-formed if the declaration bool t (arg) is well-formed, for some invented temporary t . The result is a bool prvalue.
