Calculate Sum of Numbers in Array

Even without smart pointers, you can manage memory safely in C++ using the RAII pattern. This approach:

• Prevents memory leaks.
• Simplifies exception handling.
• Keeps your code clean and maintainable.

You must implement all three. This is called the Rule of Three.

class String {
private:
    char* buffer;

public:
    String(const char* str) {
        buffer = new char[strlen(str) + 1];
        strcpy(buffer, str);
    }

    // Copy constructor
    String(const String& other) {
        buffer = new char[strlen(other.buffer) + 1];
        strcpy(buffer, other.buffer);
    }

    // Assignment operator
    String& operator=(const String& other) {
        if (this != &other) {
            delete[] buffer;
            buffer = new char[strlen(other.buffer) + 1];
            strcpy(buffer, other.buffer);
        }
        return *this;
    }

    ~String() {
        delete[] buffer;
    }

    void print() const {
        std::cout << buffer << std::endl;
    }
};

This script allows the player to move forward and backward using the Vertical axis and rotate using the Horizontal axis. The IsOwner check ensures that only the player who owns the object can control it.

• Save all your changes and go back to the main scene.
• Press Play and use the NetworkManagerHUD to start as a Host, Client, or Server.
• You should be able to control the player object and see it move on both the host and client.
