Thank you very much , in advance for your reply .......

 

No dude, i still think that the answer is (1). Go and Google. Ya, although different compilers would use different identifier rules.

Question #10

Code:

int a=10,b;
b=a++ + ++a;
printf("%d,%d,%d,%d",b,a++,a,++a);

Hmm, this is undefined- suprised nobody caught this

Question 97

Code:

int m = -14; 
int n = 6; 
int o; 
o = m % ++n; 
n += m++ - o; 
m <<= (o ^ n) & 3;  

If one of the operands is negative, the sign of the result is machine dependent...

* sys/cdef.h */
#if defined(__STDC__) || defined(__cplusplus)
#define __P(protos) protos
#else
#define __P(protos) ()
#endif
/* stdio.h */
#include <sys/cdefs.h>
div_t div __P((int, int));
The code above comes from header files for the FreeBSD implementation of the C library. What is the primary purpose of the __P() macro?
Choice 1
The __P() macro has no function, and merely obfuscates library function declarations. It should be removed from further releases of the C library.
Choice 2
The __P() macro provides forward compatibility for C++ compilers, which do not recognize Standard C prototypes.
Choice 3
Identifiers that begin with two underscores are reserved for C library implementations. It is impossible to determine the purpose of the macro from the context given.
Choice 4
The __P() macro provides backward compatibility for K&R C compilers, which do not recognize Standard C prototypes.
Choice 5
The __P() macro serves primarily to differentiate library functions from application-specific functions.
