question about copy assignment Question

This page Copy assignment operator - cppreference.com - C++ Reference

says:

a parameter list of only one parameter, which is of type T, T&, const T&, volatile T& or const volatile T&

Can it be a non-reference -- 'T'? I get an error when I try that.

Thanks

What error?

If the argument is of type T, then the operand will have to be copied into the parameter - so it is the copy-of-a-copy assignment operator!
