What does the operator /= do?

• A. Adds a value to a variable and assigns the result.
• B. Subtracts a value from a variable and assigns the result.
• C. Multiplies a variable by a value and assigns the result.
• D. Divides a variable by a value and assigns the result.

Answer: (D)

The operator divides and assigns. It takes the current value of the variable, divides it by the value on the right, and stores the result back into the same variable. It’s a shorthand for updating the variable in place using division. For example, if you have x = 10 and do x /= 2, x becomes 5 (in languages with integer division) or 5.0 (in floating-point contexts). It is equivalent to writing x = x / 2. Be mindful of division by zero, and remember that the exact result type depends on the language and the variable’s type.
