16 bit or 32 bit

Given a compiler file( .exe file) how do I know, whether compiler is 16 bit or 32 bit?

I have BC4.0, is it 16 bit compiler or 32 bit compiler?

What is difference between bcc.exe bcc32.exe?

Can anybody tell me, where can download Borland C++ 3.1?

Thanks in advance..

Code:

---

#include <stdio.h>
int main ( void )
{
    return printf( "sizeof int is %d, thus your compiler is a %d bit compiler.\n",  sizeof int, sizeof int * CHAR_BITS  );
}

---

That should do it.

what is CHAR_BITS ?

Code:

---

tmp.c: In function `main':
tmp.c:4: parse error before `int'

---

Apparently CHAR_BITS (or CHAR_BIT) isn't a standard definition. I guess you learn something new every day. (Either that or MSVC++ just doesn't have it.)

CHAR_BIT (or _BITS) is the number of bits in a single 'char'.

In this case, replace it with 8, which should do the job.

How do I know that CHAR_BIT is not a standard definition?

Thanks for ur promt reply.

#include<limits.h>

Doh. I was thinking for some odd reason that limits.h was referred to by stdilb. Thanks for the correction. And it looks like it should be "CHAR_BIT" not "CHAR_BITS".

Code:

---

printf( "sizeof int is %d, thus your compiler is a %d bit compiler.\n",  sizeof int, sizeof(int) << 3);

---

But then again this would probably seem even more confusing to a newbie.

a byte is not guaranteed to have 8 bits; using CHAR_BIT is the only correct way.
