|
|
||
| **6. Verify Installation** | ||
|
|
||
| - **Open Command Prompt**: Press `Win + R`, type `cmd`, and press `Enter`. | ||
| - **Check GCC Version**: Type `gcc --version` and press `Enter`. If installed correctly, it should display the GCC version information. | ||
|
|
||
| **7. Write Your First C++ Program** | ||
|
|
||
| - **Create a New File**: In VS Code, go to `File > New File` and save it with a `.cpp` extension (e.g., `hello.cpp`). | ||
| - **Write Code**: Type a simple C++ program: | ||
|
|
||
| ```cpp | ||
| #include <iostream> | ||
| int main() { | ||
| std::cout << "Hello, World!" << std::endl; | ||
| return 0; | ||
| } | ||
| ``` | ||
| ## Installing C++ on Linux & Ubuntu | ||
| Follow these steps to install C++ on your Linux or Ubuntu system: | ||
| #### **1. Update the Package List** | ||
| - **Open Terminal**: Press `Ctrl + Alt + T` to open the terminal. | ||
| - **Update Packages**: Run the following command to update the package list: | ||
| ```bash | ||
| sudo apt-get update | ||
| ``` | ||
|
|
||
| **2. Install the Build-Essential Package** | ||
|
|
||
| - **Install Build-Essential**: This package contains the essential tools for compiling software, including GCC (GNU Compiler Collection) and G++ (the C++ compiler): | ||
|
|
||
| ```bash | ||
| sudo apt-get install build-essential | ||
| ``` | ||
|
|
||
| - **Verify Installation**: After installation, you can verify the installation of GCC by running: | ||
|
|
||
| ```bash | ||
| gcc --version | ||
| ``` | ||
|
|
||
| This should display the GCC version installed on your system. | ||
|
|
||
| **3. Install Additional Libraries (Optional)** | ||
|
|
||
| - **Standard C++ Library**: You can install the Standard C++ Library by running | ||
|
|
||
| ```bash | ||
| sudo apt-get install libstdc++6 | ||
| ``` | ||
|
|
||
| - **Additional Libraries**: If you need additional libraries, you can install them using the apt-get install command. | ||
|
|
||
| **4. Write Your First C++ Program** | ||
|
|
||
| - **Create a New File**: Use a text editor like nano, vim, or gedit to create a new file with a `.cpp` extension: | ||
|
|
||
| ```bash | ||
| nano hello.cpp | ||
| ``` | ||
|
|
||
| - **Write Code**: Type a simple C++ program: | ||
| ```cpp | ||
| #include <iostream> | ||
| int main() { | ||
| std::cout << "Hello, World!" << std::endl; | ||
| return 0; | ||
| } | ||
| ``` | ||
| - **Save the File**: Save the file and exit the editor. | ||
| **5. Compile Your C++ Program** | ||
| - **Compile the Program:** Use the G++ compiler to compile your C++ program: | ||
| ```bash | ||
| g++ hello.cpp -o hello | ||
| ``` | ||
|
|
||
| - **Run the Program:** Execute the compiled program: | ||
| ```bash | ||
| ./hello | ||
| ``` | ||
| - You should see the output: | ||
|
|
||
| ```bash | ||
| Hello, World! | ||
| ``` | ||
|
|
||
| ## Installing C++ on macOS | ||
|
|
||
| Follow these steps to install C++ on your macOS system: | ||
|
|
||
| **1. Install Homebrew** | ||
|
|
||
| - **Open Terminal**: Press `Cmd + Space`, type `Terminal`, and press `Enter`. | ||
| - **Install Homebrew**: Homebrew is a package manager for macOS. To install it, paste the following command in Terminal and press `Enter`: | ||
|
|
||
| ```bash | ||
| /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" | ||
| ``` | ||
|
|
||
| **2. Install GCC (GNU Compiler Collection)** | ||
|
|
||
| - Install GCC: Once Homebrew is installed, use it to install GCC by running the following command in Terminal: | ||
|
|
||
| ```bash | ||
| brew install gcc | ||
| ``` | ||
|
|
||
| **3. Install Visual Studio Code** | ||
| :::note | ||
|
|
||
| - If you already have visual studio code in your Operating System then ignore this step. | ||
| ::: | ||
|
|
||
| - **Download VS Code:** Visit the [Visual Studio Code](https://code.visualstudio.com/Download) website. | ||
| - **Download for macOS:** Click on the "Download for macOS" button to get the installer. | ||
| - **Install:** Open the downloaded .zip file, move Visual Studio Code to the Applications folder, and launch it. | ||
|
|
||
| **4. Install the C++ Extension in VS Code** | ||
|
|
||
| - **Open VS Code:** Launch Visual Studio Code. | ||
| - **Go to Extensions:** Click on the Extensions icon on the left sidebar or press Cmd + Shift + X. | ||
| - **Search for C++:** Type "C++" in the search box and look for the "C/C++" extension by Microsoft. | ||
| - **Install:** Click "Install" to add the extension to Visual Studio Code. | ||
|
|
||
| **5. Set Up the Environment** | ||
|
|
||
| - **Link GCC:** On macOS, you may need to create a symlink to make g++ point to the Homebrew-installed version of GCC. Run: | ||
|
|
||
| ```bash | ||
| sudo ln -s /usr/local/bin/g++-<version> /usr/local/bin/g++ | ||
| ``` | ||
|
|
||
| - Replace < version > with the GCC version installed (e.g., `12` for `g++-12`) | ||
|
|
||
| **6. Verify Installation** | ||
|
|
||
| - **Check GCC Version:** Open Terminal and type: | ||
| ```bash | ||
| g++ --version | ||
| ``` | ||
| - This should display the version of GCC installed. | ||
|
|
||
| **7. Write Your First C++ Program** | ||
|
|
||
| - **Create a New File:** In VS Code, go to File > New File and save it with a .cpp extension (e.g., hello.cpp). | ||
| - **Write Code:** Type a simple C++ program: | ||
|
|
||
| ```cpp | ||
| #include <iostream> | ||
| int main() { | ||
| std::cout << "Hello, World!" << std::endl; | ||
| return 0; | ||
| } | ||
| ``` | ||
| - **Compile and Run:** In the Terminal within VS Code or your macOS Terminal, navigate to the directory where your file is saved and run: | ||
| ```bash | ||
| g++ -o hello hello.cpp | ||
| ./hello | ||
| ``` | ||
| - This will compile your code and run the resulting program, printing "Hello, World!" to the Terminal. |
