I am C# developer and I am almost certain that in this language an ‘int’ is always 32 bits regardless of the platform (32 vs 64 bit), a ‘long’ is always 64 bits, a float is 32 and a double 64 and so on.
There is any language where its not like that? Where the int size depends on the processor?
The sizes of int etc in C/C++ aren’t formally defined – they are compiler specific; see here for more details.
The C# designers thankfully formally dictated in the spec: int = System.Int32, long = System.Int64, etc – so you don’t have to worry about it changing. The only easily noticeable difference on x64 is
IntPtr.Size.
