Step by step solution

01

Problem

Given: Complete the following table by writing statements with combined assignment operators in the right-hand column. The statements should be equivalent to the statements in the left-hand column.
02

Understand combined assignment operators

Combined assignment operators are used to perform an operation on a variable and then immediately assign the result to that variable. They are a shorthand way of expressing these two separate operations in one expression. Some common combined assignment operators include: - += : Addition - -= : Subtraction - *= : Multiplication - /= : Division - %= : Modulus (Remainder) For example, instead of writing "a = a + b;", we can write "a += b;".
03

Provide equivalent expressions using combined assignment operators

In this step, we will create equivalent expressions for the given statements using combined assignment operators: 1. x = x * y; Equivalent expression: x *= y; 2. counter = counter + 1; Equivalent expression: counter += 1; or counter++; 3. z = z / 2; Equivalent expression: z /= 2; 4. totalCost = totalCost - discount; Equivalent expression: totalCost -= discount; 5. remainder = remainder % divisor; Equivalent expression: remainder %= divisor;
