spot on. It's architecture dependent. Here's an index:

For printing, one can use <inttypes.h>
printf("val=" PRId64 "\n", (int64_t) val);
The only problematic one is size_t. printf's %z %Z is a GNU libc extension.
Back on topic, a good general introduction to pointers, malloc etc is

Yeah, that explains why I didn't get any
compiling error on a 32bit
computer and did get on a 64bit one (where I did correct the error).
However, the latter was satisfied with %li. Apparently in c++ there is
no difference between long and long int (as far as I can find through
Google) but for c I could not find much info on a potential difference.
long is the same as long int in both. The problem is that int and long int
are both 32 bits on i386, but on x86-64 int is 32 and long int is 64 bits.
