This operator is a combination of ‘-‘ and ‘=’ operators. This operator first subtracts the value on the right from the current value of the variable on left and then assigns the result to the variable on the left. (a -= b) can be written as (a = a - b) If initially value stored in a is 8. Then (a -= 6) = 2.
