+ * Project 2: Simple Calculator
+ * Author: Bocaletto Luca
+ * Date: 2025-06-22
+ *
+ * Description:
+ * This program functions as a simple calculator capable of performing basic 
+ * arithmetic operations: addition, subtraction, multiplication, and division.
+ * It prompts the user for two numbers and an operator, then computes and displays the result.
+ *
+ * Key Concepts:
+ * - Standard input/output using scanf() and printf()
+ * - Conditional statements (if/else) for operation selection
+ * - Basic error checking (e.g., preventing division by zero)
