AmrTamerTech/clsInput_Validation_Library-CPP
A C++ library for validating user input, including numeric range checks, date validation, and safe string reading. It ensures robust and error-free input handling in console applications.
📌 C++ Input Validation Library (clsInputValidate) ⚡
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. 🚀
🌟 Project Overview
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.
✨ Features
🔢 Numeric 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.
📅 Date Validation
✅ IsDateBetween(Date, DateFrom, DateTo): Verifies if a date is within a given range.
✅ IsValidDate(Date): Ensures that a given date is valid.
🖊️ User Input Handling
✅ 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.
🚀 How It Works
🔹 Numeric Validation
- Uses template functions for flexible number validation.
- Ensures numbers fall within a valid range before returning them.
🔹 User Input Handling
- Uses
cin,cin.clear(), andcin.ignore()to manage incorrect inputs. - Prevents crashes by properly handling invalid input formats.
🔹 Date Handling
- Utilizes the clsDate class to compare and validate date values.
- Allows date range validation by checking if a date is between two others.
📚 Potential Enhancements
🛠 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.
