Hello, World!

To compile and build a C++ program, follow these steps:

1. Install a C++ Compiler: Ensure you have a C++ compiler installed, such as g++ (part of GCC) or clang++.

2. Write Your C++ Code: Create a file named main.cpp with your C++ code. For example:

   #include <iostream> int main() { std::cout << "Hello, World!" << std::endl; return 0; }

3. Open Terminal: Navigate to the directory containing your main.cpp file.

4. Compile the C++ Code: Use the g++ or clang++ command to compile your C++ code into an executable.

   g++ main.cpp -o main

5. Run the Executable: After compilation, run the generated executable.

   ./main

These steps will compile and build your C++ program, allowing you to run the resulting executable.
