Calculate Sum of Numbers in Array

RAII (Resource Acquisition Is Initialization) is a pattern where resource allocation is tied to object lifetime. When an object goes out of scope, its destructor cleans up.

Let’s build a small ScopedPointer class.

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;
    }
};

String a("Hello");
String b = a;       // deep copy
String c("World");
c = a;              // deep assignment

Now, we integrate our AST with LLVM to generate IR. Our goal is to compile the DSL expression to a function that computes and returns a double.

Implementation: CodeGen.cpp

   using UnityEngine;
   using Unity.Netcode;

   public class GameManager : NetworkBehaviour
   {
       public void StartGame()
       {
           // Code to initialize the game
       }

       public void EndGame()
       {
           // Code to handle game over state
       }

       // Example of starting a game when all players are ready
       public void CheckPlayersReady()
       {
           if (NetworkManager.Singleton.ConnectedClients.Count >= 2)
           {
               StartGame();
           }
       }
   }

• Create a simple UI that displays player statuses, such as health or scores.
• Use NetworkVariable to synchronize data like health or scores:
