Cpp JsonValue is a library for working with JSON data in C++. It provides a set of classes and functions for serializing and deserializing JSON data, as well as manipulating and querying JSON objects.

Example 1:

#include 
#include "JsonValue.h"

int main() {
    JsonValue value = JsonValue::fromString("{\"name\": \"John\", \"age\": 30}");
    std::cout << "Name: " << value["name"].asString() << std::endl;
    std::cout << "Age: " << value["age"].asInt() << std::endl;
    return 0;
}

This example shows how to parse a JSON string and access its values using the `JsonValue` class. The `fromString` method converts the JSON string to a `JsonValue` object, which can then be used to access individual elements of the JSON data.

Example 2:

#include 
#include "JsonValue.h"

int main() {
    JsonValue value = JsonValue::array({1, 2, 3, 4, 5});
    std::cout << "Size: " << value.size() << std::endl;
    for (int i = 0; i < value.size(); i++) {
        std::cout << value[i].asInt() << ", ";
    }
    std::cout << std::endl;
    return 0;
}

This example shows how to create a JSON array using the `array` method and access its values using the `JsonValue` class. The `size` method returns the number of elements in the JSON array, which can then be iterated over using a `for` loop. The package library for Cpp JsonValue is likely a custom library developed specifically for this project.
