Why Does C++ Run Faster?

Java, C#, or Python do not generate native code. Instead, they compile source code into an intermediate code. There are additional tools or programs you can use to translate this intermediate code application into machine code. While these programs convert your code to machine code, they consume various system resources.

C++'s compile and run speeds are very high because there are no overheads like in other languages.

Динамическая память

Чтобы быть успешным C++ программистом, очень важно иметь хорошее понимание того, как работает динамическая память.

В программах на языке C++, память разделена на две части:

Стек: Все ваши локальные переменные размещаются в памяти стека.

Куча: Неиспользованная программой память, которая может быть использована, когда программа динамически выделяет память.

Часто, вы не будете знать сколько памяти вам понадобится для хранения информации в определенных переменных и объем необходимой памяти будет определен при запуске программы.

Вы сможете выделить память во время выполнения программы с помощью кучи для переменных заданного типа используя оператор new, который возвращает адрес выделенной памяти.

new int;

��аким образом выделяется необходимый объем памяти для хранения целых в куче, и возвращается его адрес.

Выделенный адрес может быть сохранен в указателе, который в последствии может быть разадресован для доступа к переменной.

int *p = new int;

*p = 5;

У нас есть динамически выделенная память для целых чисел, а затем ей присвоено значение 5.

Указатель p хранится в стеке как локальная переменная и хранит выделенный в куче адрес. Значение 5 хранится по этому адресу в куче.

Освобождение памяти

Для локальных переменных в стеке, управление памятью осуществляется автоматически.

В куче, необходимо вручную управлять динамически выделенной памятью и использовать оператор delete для освобождения памяти, когда в ней больше нет необходимости.

delete pointer;

Это выражение освобождает память, на которую указывает pointer.

int *p = new int; // выделяет память

*p = 5; // передает значение

cout << *p << endl; // вывод

delete p; // освобождает память

Если забывать освобождать выделенную с помощью ключевого слова new память, то образуются утечки памяти, потому что эта память остается выделенной, пока программа не будет закрыта.

Обнуление указателя

Оператор delete освобождает память, выделенную для переменной, но не удаляет сам указатель, т.к. указатель хранится в стеке.

Указатели, которые остаются указывать на несуществующую область памяти, называются висячими указателями.

int *a = new int(5);

delete a;

a = nullptr; //Обнуление указателя

Динамическая память для массива.

Динамическая память также может быть выделена для массива.

int* a = nullptr;

a = new int [20];

delete [ ] p;

Динамическое выделение памяти полезно во многих ситуациях, к примеру, когда ваша программа зависит от введенной информации. Например, когда вашей программе необходимо получить изображение, но она не знает его возможный размер и количество памяти, необходимое для его хранения.

C++ Coding Made Simple: A Step-by-Step Guide with Online C++ Compilers

C++ is a versatile and powerful programming language used for a wide range of applications, from developing games to creating system-level software. However, for beginners and even experienced programmers, C++ can appear complex and daunting. To make the learning process more accessible and efficient, Online C++ Compilers have become invaluable tools. In this article, we will provide a step-by-step guide on how to use Online C++ Compiler to simplify C++ coding.

Why Choose Online C++ Compilers?

Before diving into the step-by-step guide, let's explore the advantages of using Online C++ Compilers:

No Installation Hassles: Online C++ Compilers eliminate the need for downloading and setting up a local development environment. You can start coding instantly, without the time-consuming installation process.

Accessibility: These online compilers are accessible from any device with an internet connection and a web browser. You can work on your C++ projects from virtually anywhere, whether it's your home, office, or even while traveling.

Cross-Platform Compatibility: Online C++ Compilers support multiple operating systems, making it easy to write code on one platform and compile it for others. This cross-platform compatibility streamlines development and testing.

Real-Time Feedback: Many online compilers offer real-time feedback as you write and test your code. This immediate feedback helps you identify and correct errors promptly, making the debugging process more efficient.

Collaboration Features: Online compilers often come with collaboration features that allow multiple users to work on the same codebase simultaneously. This fosters teamwork and enhances the coding experience for groups and partners.

A Step-by-Step Guide to Using Online C++ Compilers

Now, let's walk through the process of using Online C++ Compilers:

Step 1: Choose Your Preferred Online C++ Compiler

Begin by selecting an Online C++ Compiler that suits your needs. Some popular options include repl.it, Online GDB, and Compiler Explorer. Choose the one that aligns with your preferences.

Step 2: Access the Online Compiler

Open your web browser and navigate to the website of your chosen Online C++ Compiler.

Step 3: Create an Account (Optional)

While most online compilers allow you to start coding without creating an account, some features like saving your code and collaboration may require registration. Depending on your needs, you can choose to create an account or proceed as a guest.

Step 4: Select Your Environment

Once you're on the platform, choose the C++ environment or workspace to start writing code. The interface typically resembles an integrated development environment (IDE), complete with a code editor.

Step 5: Write Your C++ Code

Utilize the built-in code editor to write your C++ program. These online compilers often offer features like syntax highlighting, code completion, and auto-indentation to help you write clean and error-free code.

Step 6: Compile and Run Your Code

After writing your code, use the online compiler's built-in tools to compile and run your program. The output will be displayed in the console, allowing you to check for errors and verify the program's behavior.

Step 7: Debug Your Code

If you encounter issues or errors, the online compiler provides debugging tools and real-time feedback to help you identify and resolve problems promptly.

Step 8: Save and Share Your Code

Many Online C++ Compilers offer the option to save your code for future reference. You can also share your code with collaborators or instructors for feedback or collaboration.

Conclusion

Online C++ Compiler offer a user-friendly and efficient coding experience for both beginners and experienced programmers. They provide numerous advantages, including zero installation hassles, accessibility, cross-platform compatibility, real-time feedback, and collaboration features.
