What is c++ and How c++ Works & Architecture ?

What is c++ ?

C++ is a general-purpose, object-oriented programming language that was developed as an extension of the C programming language. It was developed by Bjarne Stroustrup, C++ supports both procedural and object-oriented programming paradigms and is widely used for developing system software, application software, and high-performance software.

What is top use cases of c++ ?

Top use cases of C++:

1. System software development: C++ is commonly used for developing operating systems, device drivers, and other system-level software.

2. Game development: Many popular games are built using C++ due to its performance and low-level access to hardware.

3. Embedded systems: C++ is used for creating software for microcontrollers, IoT devices, and other embedded systems.

4. High-performance applications: C++ provides low-level memory access and efficient code execution, making it suitable for applications requiring high performance, such as scientific simulations and financial analysis.

What are feature of c++ ?

1. Simple: C++ is a simple language because you can divide programs into logical units and parts. It has a lot of libraries to help you, and it supports various data types. Moreover, the Auto Keyword in C++ simplifies things further.
2. Object-Oriented Programming (OOP): C++ supports classes and objects, encapsulation, inheritance, and polymorphism, enabling developers to write modular and reusable code.
3. Mid-Level Programming Language: C++ is a programming language that combines features from both low-level and high-level languages, making it suitable for a wide range of applications.
4. Rich Library: The C++ library contains built-in functions that save time during software development and offers a wide range of functionalities.
5. Case Sensitive: C++ is case-sensitive, meaning that uppercase and lowercase letters in the code have different meanings.
6. Compiler-Based: C++ is a compiler-based language, which means the code needs to be compiled before it can be executed.
7. Dynamic Memory Allocation: C++ allows dynamic memory allocation, enabling flexible memory usage through pointers.
8. Recursion: Recursion in C++ enables code reusability by allowing functions to call themselves.
9. Fast: C++ is known for its fast execution and compilation times compared to other languages.
10. Pointers: Pointers in C++ hold the address of variables, providing increased performance and flexibility in development.

What is the workflow of c++ ?

The workflow of C++ typically involves several steps:

1. Writing the code: Create a C++ source code file with the desired functionality.

2. Compiling: Use a C++ compiler to convert the source code into machine-readable object code.

3. Linking: Combine the object code with any necessary libraries to produce an executable program.

4. Executing: Run the compiled program to see the desired output or behavior.

How to Install and Configure c++ ?

To install Dev C++ software, you need to follow the following steps:

Step 1) To get started, download Dev C++ on your Windows computer. You can find it at this link: http://www.bloodshed.net/

Step 2) Packages are available for various operating systems.

Step 3) Click on the link “Download from SourceForge” to get Dev-C++ 5.0 (4.9.9.2) with Mingw/GCC 3.4.2 compiler and GDB 5.2.1 debugger, which is a 9.0 MB package.

Step 4) This package will download a C++ executable file for Windows, which you can use to install on Windows 7, 8, XP, Vista, or 10.

Step 5) This package lets you download a C++ executable file made for Windows. It works on Windows 7, 8, XP, Vista, and 10.

• To save, click the “Save” button. It will be saved in the “Downloads” folder by default.
• Once the download is finished, find the saved .exe file and click on it to run.
• The installer will prompt you to choose a language. Select “English” and click “OK”.

• A license agreement screen will pop up. Click on “I agree” to continue.

Step 6) In this step,

1. You can see different components of Dev C++ that will be installed with this package.
2. Just click on “next” button.

Step 7) In this step,

1. By default, the destination folder is on the C drive. You can change this folder if you want, but please ensure you have enough storage space.
2. Click on “Install” button.

In the next screen, installation begins

You have successfully installed Dev C++ on your Windows. To run it, click on “Run Dev C++,” and then click on the “Finish” button.

That’s it! Now you are ready to compile your C or C++ programs with Dev C++ compiler.

Step by Step Tutorials for c++ for hello world program ?

Here step-by-step tutorial for writing a “Hello, World!” program in C++:

Step 1: Set up the development environment – Install a C++ compiler, such as GCC or Clang, on your computer. These compilers are typically included with popular IDEs like Code::Blocks or Visual Studio. – Set up your preferred Integrated Development Environment (IDE) or text editor. This will provide you with a workspace to write and run your code.

Step 2: Open a new C++ file – Open your IDE or text editor and create a new file with a “.cpp” extension. For example, you can name it “hello.cpp”.

Step 3: Write the code – In the newly created file, type the following code:

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Step 4: Save the file – Save the file with the “.cpp” extension. Step 5: Compile the code – Open a terminal or command prompt, navigate to the directory where you saved the “hello.cpp” file. – Run the following command to compile the code: For GCC:

g++ -o hello hello.cpp

For Clang:

clang++ -o hello hello.cpp

Step 6: Run the program – After successful compilation, run the executable by entering the following command:

./hello

You should see the output “Hello, World!” printed to the console. Congratulations! You have successfully written and run a “Hello, World!” program in C++.
