Theoretical Description of Increment and Decrement Operators

Increment Operator (`++`)

Prefix Increment (`++variable`) :
Description: The variable's value is increased by 1, and the new value is immediately used in any expression. The increment happens before the variable’s value is utilized.

Example : If a variable `x` is initially `5`, then `++x` results in `6`. Thus, the new value of `x` is `6`, and this updated value is used in subsequent operations or expressions.
Postfix Increment (`variable++`):
Description: The current value of the variable is used in the expression first, and then the variable’s value is increased by 1. The increment happens after the current value is used.
Example: If a variable `x` is initially `5`, then `x++` results in `5` being used in the expression, and `x` is incremented to `6` afterward. Thus, the value used is `5`, but the variable `x` becomes `6` after the operation.

Decrement Operator (`--`)

Prefix Decrement (`--variable`):
Description: The variable's value is decreased by 1, and the new value is immediately used in any expression. The decrement happens before the variable’s value is utilized.
Example: If a variable `x` is initially `5`, then `--x` results in `4`. Thus, the new value of `x` is `4`, and this updated value is used in subsequent operations or expressions.

Postfix Decrement (`variable--`):
Description: The current value of the variable is used in the expression first, and then the variable’s value is decreased by 1. The decrement happens after the current value is used.
Example: If a variable `x` is initially `5`, then `x--` results in `5` being used in the expression, and `x` is decremented to `4` afterward. Thus, the value used is `5`, but the variable `x` becomes `4` after the operation.

Summary

Prefix Operators: Modify the value first, then use it in expressions.
Postfix Operators: Use the current value in expressions first, then modify the value.
