Make a basic demo I can easily copy-paste whenever I need a simple program.

To compile and run (assuming you've already `cd`ed into this dir):
1. In C++
    mkdir -p bin && g++ -Wall -Wextra -Werror -O3 -std=c++17 -save-temps=obj hello_world_basic.cpp \
    -o bin/hello_world_basic && bin/hello_world_basic

    static_assert(1 == true, "1 must equal true");
    std::cout << "the static_assert passed" << std::endl;

SAMPLE OUTPUT:

In C++:

    eRCaGuy_hello_world/cpp$ mkdir -p bin && g++ -Wall -Wextra -Werror -O3 -std=c++17 -save-temps=obj hello_world_basic.cpp \
    >     -o bin/hello_world_basic && bin/hello_world_basic
    This is the start of `main()`.
      Hello world.
    This is the end of `main()`.
    the static_assert passed
