HOW TO WRITE, COMPILE AND RUN C++ CODE ON LINUX KALI

Developing a C++ Program on Kali Linux Without Installing Additional Software

This article is for hackers who want to develop a C++ program on Kali Linux without installing any additional software.

Some might say you need to install a separate compiler or extra tools to write and run a simple C++ program on Kali Linux. However, I’ll show you how to do it right out of the box.

Pre-installed C++ Compiler in Kali Linux

Kali Linux comes with a pre-installed C++ compiler called g++. We will use this to write and compile a basic "Hello, World!" program.

Step 1: Check if g++ is Installed

Open your terminal and run the following command:

g++ -v

If the compiler is installed, you should see version details. If not, you will get an error message.

Step 2: Create a C++ File

In your terminal, type:

nano MyCpp.cpp

This will create a C++ file and open it in the Nano editor.

Step 3: Write the C++ Code

Once Nano opens, enter the following C++ code:

#include <iostream>
using namespace std;

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

Press Ctrl + X, then Y, and hit Enter to save and exit.

Step 4: Compile the Code

Run the following command in your terminal:

g++ MyCpp.cpp

If everything goes well, the command will return to the prompt without any message. You’ll notice that a new file named a.out has been created in the same directory. This is the compiled binary of your program.

Step 5: Run Your C++ Program

To execute your newly created program, type:

./a.out

Your program should display:

Hello, World!

Conclusion

That was easy, wasn’t it? Now you can start building more complex programs using C++ on Kali Linux. Thanks for reading!
