how to complie with c++ 17

To compile a C++ program with C++17, you can follow these steps:

  1. Ensure you have a C++17 compatible compiler: First, make sure that you have a C++ compiler that supports C++17. Popular compilers like GCC, Clang, and MSVC have C++17 support in their recent versions. Check the documentation or the compiler's website to verify if your compiler version supports C++17.

  2. Set the C++ language standard: Use the appropriate compiler flag or setting to specify the C++17 language standard. The flag may vary depending on the compiler you are using. Here are some examples:

  3. For GCC and Clang, use the -std=c++17 flag: bash g++ -std=c++17 my_program.cpp -o my_program

  4. For MSVC, use the /std:c++17 flag: bash cl /std:c++17 my_program.cpp

  5. Compile your program: Once you have set the C++17 language standard, compile your program using the chosen compiler. Specify the input source file (e.g., my_program.cpp) and optionally provide an output file name (e.g., -o my_program for GCC/Clang).

  6. Run the compiled program: If the compilation is successful, you should have an executable file. Run the compiled program using the appropriate command for your operating system.

That's it! By following these steps, you should be able to compile a C++ program with C++17 language standard support.
