memory usage of an object's member functions

[Randy Yates]

If a member function uses no static local variables, then is only one
"pure root" of that member function's code used by all instantiated
objects or is its code duplicated for each instantiated object?

objects or is its code duplicated for each instantiated object?

Usually, if the function is not declared 'inline' (either explicitly or
implicitly), the compiler has no reason to duplicate its body anywhere,
so, _usually_ only one body of any function exists in the final code.
