Is int in C Always 32-bit?

AFAIK, in Pascal size of Integer depends on the platform (on 32-bit computers it has 32 bits, and on 64-bit computers it has 64 bits).

Is this the same in C (I mean, on 32-bit computers its size is 32 bits, and on 64-bit it is 64)?

Answer 1

Pretty much but compiler has control. Use the sizeof operator if you just want to check what is happening in your environment. stddef.h will include types like int64_t (I think in that file) if you need to make sure # of bytes is fixed and not leave this up to environment/compiler.
