macOS how the size of an integer is decided?

[ChrisA]

There's something I don't quite understand. sizeof() returns a value of type size_t which, if I remember correctly, is defined as unsigned int. So I guess the results above are fine for 32bit architecture, but for 64 bit size_t wouldn't be big enough for all cases.

Out of interest perhaps you could print out the result of sizeof( size_t )?

thanks

"size_t" is the type that is used to hold the length of a object in memory, so by definition size_t is long enough to hold the length of a object in memory. Or to say it another way, it is impossible to define an object larger than what would fit in a variable of type size_t.
