Compound Assignment Operators in C++

Let us see the Compound Assignment Operators in C++.

Operators	What the operators will do?
<<=	Shift the value of the 1st operand left the number of bits specified by the value of the 2nd operand and then store the result in the Variable specified by the 1st operand.
%=	Variable specified by the 1st operand = Take modulus of the 1st operand specified by the value of the 2nd operand
^=	Obtain the bitwise exclusive OR of the 1st and 2nd operands; store the result in the Variable specified by the 1st operand.
\|=	Obtain the bitwise inclusive OR of the 1st and 2nd operands; store the result in the Variable specified by the 1st operand.
&=	It can take the bitwise AND of the 1st value and the 2nd operands value and then store the result in the Variable that can be specified by the 1st operand.
+=	Variable specified by the 1st operand = value of the 2nd operand + value of the 1st operand
–=	Variable specified by the 1st operand = value of the 2nd operand – value of the 1st operand.
>>=	Shift the value of the 1st operand right the number of bits specified by the value of the 2nd operand; store the result in the Variable specified by the 1st operand.
* =	Variable specified by the 1st operand = value of the 1st operand * value of the 2nd operand
/=	Variable specified by the 1st operand = 1st operand / value of the 2nd operand
