Should I use 'long' instead of 'int' on 64-bits in langs with fixed type size (like Java, C#)

Question

In 10, or even 5 years there will be no [Edit2: server or desktop] 32-bit CPUs.

So, are there any advantages in using int (32bit) over

Answer 1

Sorry for the C++ answer.

If the size of the type matters use a sized type:

• uint8_t
• int32_t
• int64_t
• etc

If the size doesn't matter use an expressive type:

• size_t
• ptrdiff_t
• ssize_t
• etc

I know that D has sized types and size_t. I'm not sure about Java or C#.
