Assignment Operators

Perl Assignment Operators:

Assume variable $a holds 10 and variable $b holds 20 then:

Operator	Description	Example
=	Simple assignment operator, Assigns values from right side operands to left side operand	$c = $a + $b will assigne value of $a + $b into $c
+=	Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand	$c += $a is equivalent to $c = $c + $a
-=	Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand	$c -= $a is equivalent to $c = $c - $a
*=	Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand	$c *= $a is equivalent to $c = $c * $a
/=	Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand	$c /= $a is equivalent to $c = $c / $a
%=	Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand	$c %= $a is equivalent to $c = $c % a
**=	Exponent AND assignment operator, Performs exponential (power) calculation on operators and assign value to the left operand	$c **= $a is equivalent to $c = $c ** $a
