How to compile C++?

To compile a C++ program, you typically use a compiler like g++. Here’s a simple step-by-step guide:

Write your C++ code: Save your code in a file with a .cpp extension, for example, program.cpp.
Open your terminal: Navigate to the directory where your .cpp file is located.
Compile the code: Use the following command:
```
g++ program.cpp -o program
```
- This command compiles program.cpp and creates an executable named program.
Run the compiled program: Execute the program with:
```
./program
```

Make sure you have g++ installed on your system. If you need help with installation or have any other questions, feel free to ask!
