Why sizeof(string) = 4?

[gary]

Hi,
Who can say something about the class of string? Why sizeof(string) = 4?

Thanks.

sizeof(std::string) might be four on some implementations, 8, 16 or 24
on others. It all depends on the actual implementation of std::string
of which the standard does not say anything.

Well, why not?

Probably because your specific implementation of that class uses a
single pointer to the memory of the string. Which in this case is 4
bytes (32 bits). All this depends on implementation tho.

If you want to know the number of characters in your string, you ought
to use the size() member.
