What does the decrement operator (--) signify?

Increase by one unit
Multiply by two
Decrease by one unit
Divide by two

The correct answer is: Decrease by one unit

The decrement operator (--) decreases the value of a given variable by one unit. It does not increase the value (option A) nor does it multiply or divide the value (options B and D). The only action the decrement operator performs is decreasing the value by one unit. It is important to note that this operator only works on numerical variables, as it cannot be applied to string or boolean data types. Therefore, the correct answer is C Decrease by one unit.
