Calculate Sum of Numbers in Array

template <typename T>
class ScopedPointer {
private:
    T* ptr;

public:
    explicit ScopedPointer(T* p = nullptr) : ptr(p) {}

    ~ScopedPointer() {
        delete ptr;
    }

    T& operator*() const { return *ptr; }
    T* operator->() const { return ptr; }
    T* get() const { return ptr; }

    void reset(T* p = nullptr) {
        if (ptr != p) {
            delete ptr;
            ptr = p;
        }
    }

    // Prevent copy
    ScopedPointer(const ScopedPointer&) = delete;
    ScopedPointer& operator=(const ScopedPointer&) = delete;
};

For arrays:

In C++, copying objects can lead to serious bugs if you're dealing with raw pointers. By default, C++ uses shallow copy, which means only the pointer's value is copied—not the data it points to.

This tutorial covers:

#ifndef DSL_PARSER_H
#define DSL_PARSER_H

#include "Lexer.h"
#include "AST.h"
#include <memory>

class Parser {
public:
    Parser(Lexer& lexer);
    std::unique_ptr<ASTNode> parseExpression();

private:
    Lexer& lexer;
    Token currentToken;

    void eat(TokenType type);
    std::unique_ptr<ASTNode> factor();
    std::unique_ptr<ASTNode> term();
};

#endif // DSL_PARSER_H

Implementation: Parser.cpp

• In the Hierarchy window, right-click and create a new 3D Object > Plane to serve as the ground.
• Create a 3D Object > Cube to act as the player character.
• Position the cube above the plane so that it is ready to fall due to gravity.
• Add a Camera and Light to the scene if they are not already present.

• Right-click in the Hierarchy and create an empty GameObject. Name it "NetworkManager."
• Add the NetworkManager component by clicking Add Component and searching for "NetworkManager."
• Also, add the NetworkManagerHUD component to provide basic controls for starting and stopping the server or client.

The following Python code demonstrates how to create a one-dimensional array using NumPy:

import numpy as np

# Create a 1D array
arr = np.array([1, 2, 3, 4, 5])
print(arr)
