Answer / susie

Answer :

No output

Explanation:

The else part in which the printf is there becomes the else
for if in the assert macro. Hence nothing is printed.

The solution is to use conditional operator instead of
if statement,

#define assert(cond) ((cond)?(0): (fprintf (stderr,
"assertion failed: \ %s, file %s, line %d \n",#cond,
__FILE__,__LINE__), abort()))

Note:

However this problem of “matching with nearest else” cannot
be solved by the usual method of placing the if statement
inside a block like this,

#define assert(cond) { \

if(!(cond)) \

(fprintf(stderr, "assertion failed: %s, file %s,
line %d \n",#cond,\

__FILE__,__LINE__), abort()) \

}
