 * Program Name : Find ASCII Value
 * File Name    : 019-Find-ASCII-Value.java
 * Class Name   : FindASCIIValue
 *
 * Description:
 * This program demonstrates how to find the ASCII value of a character
 * in Java. Every character is internally represented by a numeric value
 * based on the ASCII (American Standard Code for Information Interchange)
 * character set for standard characters.
 *
 * Objective:
 * - Understand the relationship between characters and their ASCII values.
 * - Learn how implicit type conversion converts a char into an int.
 * - Display the ASCII value of a given character.
