Chapter 5: Problem 18

When the increment or decrement operator is placed after the operand (or to the operand's right), the operator is being used in __________mode.

Short Answer

Expert verified

Answer: When the increment or decrement operator is placed after the operand, it is called "postfix" mode. In postfix mode, the value of the variable is used in the expression first and then the increment or decrement operation is performed on the variable. The new value of the variable will only be used in the next expression where it is called upon.

Step by step solution

Identify the operator and its usage

The question asks about increment or decrement operators placed after the operand (to the operand's right). In programming languages like C, C++, and Java, these are operators like ++ and --. When placed after the variable, they increase or decrease the value of the variable after performing the operation in the expression where they were used.

Determine the mode

When increment or decrement operators are placed after the operand, it is called "postfix" mode. In postfix mode, the value of the variable is used in the expression first and then the increment or decrement operation is performed on the variable. The new value of the variable will only be used in the next expression where it is called upon. For example, in a programming language like C, int x = 5; int y = x++; After executing these two lines of code, x will have the value 6, and y will have the value 5. This is because, in postfix mode, the value of x is assigned to y first (5) and then the increment operation is performed on x (5+1=6).
