What is the decrement operator in C?
Correct answer: B. Unary operator
- A. Assignment operator
- B. Unary operator
- C. Ternary operator
- D. Binary operator
Explanation
The correct answer is: (b) Unary operator. Decrement operator (--) is a unary operator that subtracts 1 from the value of its operand (the variable it operates on). It can be used in two forms:Prefix decrement: --x - In this form, the decrement operation is performed before the value is used. For example, if x is 5, then --x becomes 4, and then 4 is used in the expression.Postfix decrement: x-- In this form, the current value of the variable is used first, and then the decrement operation is performed. For example, if x is 5, then x-- uses the value 5 in the expression, and then x becomes 4.
