A small doubt on ptrdiff_t

[ajaygargnsit]

Hi

I am clear about the nuisances about ptrdiff_t. There is just one thing that I need to know :

Suppose we need to display the value of an object (say 'x') of ptrdiff_t. Then what format specifier should be used, assuming I am using printf tp print on stdput ??

I guess %ld or %lx would do fine.

kind regards,

Jos

Did you open the post on ptrdiff_t before? If you did, do not double posts. If you did not can you please clearify your question

[ajaygargnsit]

well, if that is the case, then why do we need ptrdiff_t at the first place. Can it not be that the pointer difference be stored in a long variable, since we are ultimately casting it to long type itself in printf statement ?

Any ideas?
