You mean versions 2.7.2 and 3.2.1.

That means you may need to upgrade your C++ code to C++ standard code.

That's how you correct it.

: lots of errors as it doesn't find cout and the functions.

Then you need to correct your program.

1. Yes and hide the fact you're not using standard C++, or
2. No and live with the warning or
3. Use standard C++ and correct your program.


Right,
