A lightweight and efficient C++ utility class designed to validate user input, ensuring data integrity and seamless error handling. This library provides robust number and date validation functions for console applications. 🚀

The clsInputValidate class helps developers ensure that user input meets required constraints, preventing invalid entries and enhancing program reliability. It includes functionalities such as:

✔️ Numeric validation: Ensures input falls within a valid range.
✔️ Date validation: Checks if a date is valid and falls within a given range.
✔️ User input handling: Reads and processes numbers and strings safely.
✔️ Error handling: Prevents incorrect inputs and prompts re-entry.

This class is designed for C++ console-based applications that require user input validation.

✅ IsNumberBetween(Number, From, To): Checks if a number is within a specified range.
✅ ReadNumber<T>(): Reads a number from user input and ensures validity.
✅ ReadNumberBetween<T>(From, To): Reads a number and validates it against a given range.

✅ IsDateBetween(Date, DateFrom, DateTo): Verifies if a date is within a given range.
✅ IsValidDate(Date): Ensures that a given date is valid.

✅ ReadShortNumber(): Reads a short value from the user.
✅ ReadIntNumber(): Reads an int value from the user.
✅ ReadFloatNumber(): Reads a float value from the user.
✅ ReadDoubleNumber(): Reads a double value from the user.
✅ ReadString(): Reads and returns a string input from the user.

• Uses template functions for flexible number validation.
• Ensures numbers fall within a valid range before returning them.

• Uses cin, cin.clear(), and cin.ignore() to manage incorrect inputs.
• Prevents crashes by properly handling invalid input formats.

• Utilizes the clsDate class to compare and validate date values.
• Allows date range validation by checking if a date is between two others.

🛠 Extended Error Handling: More detailed error messages for invalid input cases.
🗄 Logging Support: Store incorrect attempts for debugging or analytics.
🔄 Customizable Validation Rules: Allow developers to define custom validation rules dynamically.
🌎 Localization Support: Multi-language error messages for international applications.
