help needed on C program exection

[sahitya]

Hi ,

Can any one calrify me giving answers to the questions based on the c program given below.

char * b, q, *r;
b=getbuf();
q = *b;
r= anotherfunction(b);
/* we want to use ‘q’ and  ‘r’ here*/
char * getbuf()
{
   char buff[8];
/* unspecified, buff defined here *./
  return (char *) buff;
}
 

1. What will be in variable ‘q’ after line q=*b is executed? Under what conditions might this not be so?



2. Is there an alternative, but equivalent, way to write the line char * getbuf() If so, what is it?



3. Is getbuf() a reasonable function?



4. Will getbuf() execute at all?



5. Please comment on line return (char *) buff;



6. Is getbuf() good practice, and why?



7. What line not given should be provided for compilation?

Please I need help very urgently .

Regards
Sahitya
