Q12 You have been assigned the following seemingly working C code, which processes files controlling the behaviour of a system. You observe that, after obtaining several ERR_MALFORMED errors, subsequent calls to fopen fail due to too many files being open: int process_file(char *name) { FILE *p = fopen(name, "r"); if (p = NULL) return ERR_NOTFOUND; while (...) { ... if (...) return ERR_MALFORMED; process_one_option(); ... } fclose(p); return SUCCESS; } (i) Explain how to fix the program using facilities in C. (2 marks) (ii) Nowysuppose the function above was part of a system written in C++ (but still using the C file- processing commands such as fopen and fclose), and that process_one_option() might raise one or more exceptions. Using a class with a destructor, show how to fix the "too many files open" bug above.?
