C++ Operator Classification

    The C++ programming language offers different types of operators. These operators are used in expressions that evaluate to a single value. Sometimes the operator is used in decision making that changes the flow of the program.

    Here is the diagram that classifies C++ operators into different categories.

    Arithmetic Operators

    OperatorDescription
    +Addition operation
    –Subtraction operation
    *Multiplication
    /Division operation
    %Mod operation ( gives remainder)

    Assignment Operators

    Operator Description
    =Assigns right-value to left-value
    +=Assigns ( left-value + right-value) to left-value
    -=Assigns ( left-value – right-value) to left-value
    *=Assigns ( left-value * right-value) to left-value
    /=Assigns ( left-value/ right-value ) to left-value
    %=Assigns (left-value % right-value) to left-value
    >>=Right-shift and then assign to left-value
    <<=Left-shift and then assign to left-value
    &=Bitwise AND operation and then assign to left-value
    |=Bitwise OR operation and then assign to left-value.
    ~=Bitwise complement and then assign to left-value

    Note: In the following expression A is left-value and 10 is right-value.

    A = 10;

    Logical Operators

    OperatorDescription
    <Less than
    >Greater than
    <=Less than or equal to
    >=Greater than or equal to
    == Equal to
    !=Not equal to
    &&AND operation
    ||OR operation
    !NOT operation

    Bitwise Operators

    OperatorDescription
    &Bitwise AND operation
    |Bitwise OR operation
    ^Bitwise Exclusive OR (XOR) operation
    >>Bitwise Right Shift
    <<Bitwise Left Shift
    ~Bitwise Complement

    Unary Operators

    OperatorDescription
    *Pointer reference
    &Reference to address of a variable
    –Negative value
    !Not operation
    ~Bitwise complement
    ++Increment operator
    —Decrement operator
    typeForced conversion to another data type
    sizeofSize of a data type in bytes
