What does the C++ standard state the size of int, long type to be?

Question

I\'m looking for detailed information regarding the size of basic C++ types. I know that it depends on the architecture (16 bits, 32 bits, 64 bits) and the compiler.

Answer 1

We are allowed to define a synonym for the type so we can create our own "standard".

On a machine in which sizeof(int) == 4, we can define:

typedef int int32;

int32 i;
int32 j;
...

So when we transfer the code to a different machine where actually the size of long int is 4, we can just redefine the single occurrence of int.

typedef long int int32;

int32 i;
int32 j;
...
