If you encounter the error 'stdin' was not declared in this scope when you run the C++ programs here, you need to add #include <cstdio> to the C++ program.

See if the environment variable CPLUS_INCLUDE_PATH is already set to the \__libraries\ directory:
set CPLUS_INCLUDE_PATH
If it is not, then set it to the [**==change-me-to-root-dir==**]\_libraries\
set CPLUS_INCLUDE_PATH=[**==change-me-to-root-dir==**]\__libraries\
g++ 2024-02-29-hello-world-with-unit-tests.cpp & a
Or, if you want to specify the name of the .exe file
set CPLUS_INCLUDE_PATH=[**==change-me-to-root-dir==**]\__libraries\
g++ 2024-02-29-hello-world-with-unit-tests.cpp -o hello-world
hello-world
To tell the compiler to use specific version of C++, like C++11 only (with features of C++14 excluded):
g++ -std=c++11 2024-02-29-hello-world-with-unit-tests.cpp & a
Other g++ flags for specifying compiler version to use:
g++ -std=c++98 ...
g++ -std=c++14 ...
g++ -std=c++17 ...
g++ -std=c++2a ...
