/*
 * ============================================================================
 * Program Name : Increment and Decrement Operators
 * File Name    : 010-Increment-and-Decrement-Operators.java
 * Class Name   : IncrementAndDecrementOperators
 *
 * Description:
 * This program demonstrates the use of increment (++) and decrement (--)
 * operators in Java. It also explains the difference between pre-increment,
 * post-increment, pre-decrement, and post-decrement operators.
 *
 * Increment and Decrement Operators:
 * ++  Increment Operator
 * --  Decrement Operator
 *
 * Types:
 * 1. Pre-Increment  (++variable)
 * 2. Post-Increment (variable++)
 * 3. Pre-Decrement  (--variable)
 * 4. Post-Decrement (variable--)
 *
 * Objective:
 * - Understand increment and decrement operators.
 * - Learn the difference between pre and post operators.
 * - Observe how variable values change during execution.
