A simple, robust input/output library designed for SZABIST students to handle console input validation and user interaction in C++.

• Type-safe input validation - Robust validation for all numeric types
• Error handling - Clear error messages and automatic retry on invalid input
• Cross-platform compatibility - Works on Windows, Linux, and macOS
• Header-only library - Easy to integrate into any project
• Multiple input types - Support for integers, strings, characters, booleans, dates, and times
• Interactive menus - Built-in choice selection and confirmation dialogs
• Console utilities - Screen clearing and pause functionality

1. Download the zablib.h file
2. Include it in your C++ project:

   #include "zablib.h"

3. Create a ZabLib instance and start using it:

   ZabLib io;
   int age = io.get_int("Enter your age: ");

#include "zablib.h"

int main() {
    ZabLib io;
    
    // Get different types of input
    int age = io.get_int("Enter your age: ");
    std::string name = io.get_line("Enter your full name: ");
    char grade = io.get_char("Enter your grade (A-F): ");
    bool isStudent = io.get_bool("Are you a student? (y/n): ");
    
    std::cout << "Hello " << name << ", age " << age << std::endl;
    return 0;
}

#include "zablib.h"

int main() {
    ZabLib io;
    
    const char* options[] = {
        "View Profile",
        "Edit Settings", 
        "Logout",
        "Exit"
    };
    
    int choice = io.get_choice(options, 4, "Main Menu:");
    
    switch(choice) {
        case 0: std::cout << "Viewing profile..." << std::endl; break;
        case 1: std::cout << "Editing settings..." << std::endl; break;
        case 2: std::cout << "Logging out..." << std::endl; break;
        case 3: std::cout << "Goodbye!" << std::endl; break;
    }
    
    return 0;
}

#include "zablib.h"

int main() {
    ZabLib io;
    
    std::string birthDate = io.get_date("Enter your birth date");
    std::string appointmentTime = io.get_time("Enter appointment time");
    
    std::cout << "Appointment scheduled for " << appointmentTime 
              << " on " << birthDate << std::endl;
    
    return 0;
}

ZabLib automatically validates all input and provides helpful error messages:

• Numeric validation: Ensures input is within valid range for the data type
• Format validation: Checks date/time formats match expected patterns
• Type validation: Prevents invalid conversions and overflow
• Retry mechanism: Automatically prompts user to re-enter invalid input

The library provides clear, user-friendly error messages:

Error: 'abc' is not a valid integer. Please try again.
Error: unsigned int cannot be negative. Please try again.
Error: Please enter date in MM/DD/YYYY format.
Error: Please enter 'y' or 'n'.

• Windows: Uses cls command for screen clearing
• Linux/macOS: Uses clear command for screen clearing
• All platforms: Cross-platform compatible input handling

• C++11 or later
• Standard C++ library
• Console/terminal environment

Simply download zablib.h and include it in your project. No compilation or linking required.
