How do you determine the size of an object in C++?

Question

For example, say I have a class Temp:

class Temp
{
    public:
        int function1(int foo) { return 1; }
        void function2(int bar) { foobar = bar; }         


        

Answer 1

If you want detailed information about how objects are represented in memory at run-time, the ABI (Application Binary Interface) specification is the place to look. You'll need to look determine which ABI your compiler implements; for example, GCC versions 3.2 and above implement the Itanium C++ ABI.
