              The increment operator (++) provides a shortcut to increase the value of a variable by one.The decrement operator (--) simply subtracts a value of one from a variable.The increment and decrement operators are helpful when used with loop counter variables.

Description:

  • Assign an initial integer value to a variable.This variable will be used to illustrate the increment and decrement operators.
  • Type the increment operator (++) before the variable name and use the Expression tag to print the result to the Web page.The variable will be incremented by one before it is displayed.
  • Type the decrement operator (--) before the variable name and use the Expression tag to print the result to the Web page.The variable will be decreased by one before it is displayed.

Using Increment Operator

The value of i is 4
The value of ++i is 5

Using Decrement Operator

The value of i is 5
The value of --i is 4
