Can someone pls explain the difference between these two especially in
terms of scope... one example i have come across is
1.
char *xxx(int n)
{
char *retbuf = malloc(25);
if(retbuf == NULL)
return NULL;
sprintf(retbuf, "%d", n);
return retbuf;
}
2.
char *xxx(int n)
{
char retbuf[25];
sprintf(retbuf, "%d", n);
return retbuf;
}
First one is correct and the second one is wrong... why does the scope
of retbuf extends to the calling function...
am just a beginner so ignore the stupidity(if any).....
