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.

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:


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