BigNumber Library

This repository contains a C++ library for working with BigNumber objects, which represent large numerical values stored as strings of decimal digits. The library provides support for standard comparison and mathematical operations, such as <, >, ==, +, and -. It also includes an overload for the << operator to print BigNumber objects to the console.

Installation

To use this library in your C++ project, follow these steps:

1. Clone the repository or download the source code files.
2. Include the header.h file in your project.

#include "header.h"

BigNumber Class

The BigNumber class is an abstract base class that defines the common interface for working with large numbers. It includes the following pure virtual member functions:

• bool operator<(BigNumber&): Overloaded operator to check if one BigNumber object is less than another.

• bool operator>(BigNumber&): Overloaded operator to check if one BigNumber object is greater than another.

• bool operator==(BigNumber&): Overloaded operator to compare two BigNumber objects.

• BigNumber& operator+(BigNumber&): Overloaded operator to add two BigNumber objects.

• BigNumber& operator-(BigNumber&): Overloaded operator to subtract two BigNumber objects.

BigDecimalInt Class

The BigDecimalInt class is derived from BigNumber and represents an integer number with a decimal point. It provides methods to compare, add, and subtract values with other BigNumber objects. The constructor takes a string as a parameter to initialize the instance.

BigReal Class

The BigReal class is also derived from BigNumber and is designed to hold large real numbers. It implements addition, subtraction, comparison, and equality operators. The constructor takes a string as a parameter to initialize the instance.

Example

Here's a simple example demonstrating the usage of the BigNumber library:

#include <iostream>
#include "header.h"

int main() {
    // Create BigDecimalInt objects
    BigDecimalInt num1("123456789");
    BigDecimalInt num2("987654321");

    // Add two BigDecimalInt objects
    BigNumber& sum = num1 + num2;

    // Print the result
    std::cout << "Sum: " << sum << std::endl;

    return 0;
}
