(15pt) Consider the function below, where you get a pointer pi to the first and a pointer p2 to the last character of the same string. The function should return a pointer to the character in the middle of the string (in case of an even size consider the leftmost). char *midchar (char *p1, char *p2) ( return (p1 + p2) / 2; A thoughtful 212 student should notice that adding together pointers is likely to be disastrous Memory addresses tend to be very large. The operation above is very likely to lead to overflow Rewrite the function above in order to avoid the overflow
