This article provides a concise guide on how to identify the version of the GCC C++ compiler installed on a Windows, Linux, or Mac computer.

You might think of scouring your computer’s file system to find the installation location of the compiler, then checking its version there. However, there’s a more efficient method.

To swiftly verify the compiler’s version, simply open the command prompt on your Windows PC, e.g., by typing cmd in your search field, and enter the following command:

g++ --version

Once executed, the command prompt will promptly display the installed version of your GCC C++ compiler.

How to Check the C++ Version

First, you’ll learn how to check the C++ version on three popular platforms: Windows 10 Command Prompt, Linux or Mac, and Ubuntu. 😃

🎨🖌 Code is art! So I’ll provide some art pics throughout the article. 👇

On Windows 10 Command Prompt

To check your C++ version on Windows 10, you’ll need to use the Command Prompt. First, you’ll need to have GCC (GNU Compiler Collection) installed on your system. If you don’t have GCC installed, download it from the official website.

Once GCC is installed:

  1. Open the Command Prompt.
  2. Type gcc -v, then press Enter.

The actual version of the compiler will be displayed, along with information about the version of the C++ standard it supports. ✅

On Linux or Mac

In a Linux or Mac environment, checking the C++ version is quite similar. First, make sure you have GCC or an alternative like Clang installed.

To check the C++ version using GCC:

  1. Open the terminal.
  2. Type g++ -v, then press Enter.

If you are using Clang:

  1. Open the terminal.
  2. Type clang++ -v, then press Enter.

In both cases, you will see the version of the compiler and the supported C++ standard. 🖥

On Ubuntu

For Ubuntu users, here’s a quick refresher. As Ubuntu is based on Linux, the process is almost identical to the Linux instructions above. To check the C++ version:

  1. Open the terminal.
  2. Type g++ -v (if using GCC) or clang++ -v (if using Clang), then press Enter.

You will then see the version of the compiler and the supported C++ standard. Happy coding! 🚀

Is C++ Installed, and What Version is Installed?

This section will guide you on how to verify C++ installation and find out its version using Windows 10 command prompt (cmd). Let’s dive in! 😃

In Windows 10 Cmd

To check if C++ is installed and its version, you can use the command prompt in Windows 10. Open a cmd window by pressing Win + R, typing cmd, and hitting Enter.

In the command prompt, enter the following command:

g++ --version

This command will display the installed version of the GNU C++ Compiler (g++) if it is installed. If you see an error message or no output, it’s likely that the g++ compiler is not installed on your system. You may consider installing a suitable version of the compiler such as MinGW for your development needs.👩‍💻

Visual C++ Version in Cmd

For those using Microsoft’s Visual C++ compiler, you can also determine the installed version through the command prompt. First, open the “Developer Command Prompt for Visual Studio” by searching it in the Start menu. In the Developer Command Prompt, type the following command:

cl

This command will display the installed Visual C++ version if it is set up correctly. If the command is not recognized or there’s no output, you may need to verify whether Visual Studio is installed or check the environment variables for proper configuration. 🛠

How to Run C++ on Windows 10

Getting your C++ compiler and environment set up in Windows can be a bit tricky. Don’t worry! In this section, we’ll guide you through the process of running C++ on Windows 10. 👍

First, you need to install a C++ compiler. The most popular one is the MinGW compiler, which supports both GCC and G++ compilers. Follow the instructions provided by the linked resource to get your compiler installed.

Once your compiler is installed, it’s time to set up your environment variables. To do this, follow these steps:

  1. Right-click on the Computer icon and select “Properties”.
  2. Click on “Advanced system settings” and then “Environment Variables”.
  3. Under “System variables”, look for the “Path” variable and click “Edit”.
  4. Click “New”, and type the path where your MinGW is installed, typically C:\MinGW\bin.
  5. Click “OK” to save your changes.

Great! Now your C++ environment is all set up. 🎉

To run a C++ program, open the Command Prompt by pressing the Windows key, typing “cmd”, and hitting Enter.

To make sure your compiler is working, type the following command:

g++ --version

Now you can compile and run your C++ programs. To do this, navigate to the folder where your .cpp file is saved using the cd command.

For example:

cd C:\Users\yourusername\Documents\cpp_projects

To compile your file, type:

g++ yourfile.cpp -o youroutput

Replace “yourfile.cpp” with the name of your C++ file and “youroutput” with the desired output file name. Finally, run your compiled program by typing:

youroutput

And that’s it! Now you know how to run C++ programs on Windows 10.

Understanding C++ Versions and Standards

To check the version of the C++ Python bindings on your system, you can use the following steps. This is important, as the bindings connect C++ and Python code and facilitate smooth interaction between the two languages.

  1. Install Python and the Python C++ bindings: Make sure you have Python installed on your system. Additionally, install the required C++ Python bindings, such as Boost.Python or pybind11.
  2. Create and run a simple C++ Python script: Write a small piece of code using the C++ Python bindings, then compile and run the script. If the script executes successfully, you can assume that the bindings are correctly installed and working.
#include<boost/python.hpp>

int main() {
    Py_Initialize();
    PyRun_SimpleString("import sys; print(sys.version)");
    Py_Finalize();

    return 0;
}
  1. Check the Python version displayed: The output of the script will display the Python version used in conjunction with the C++ Python bindings.

Remember to keep your code and bindings up-to-date and maintain compatibility between the C++ and Python versions you’re using. With these additional checks, you can ensure a seamless coding experience with both C++ and Python. Happy coding! 😃
