    I need to know why you cant write a program to find out.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Mmm - 5 seconds to try it with your own compiler?
    Several hours to wait for replies telling you to use your compiler.

    That's tough.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
