Hi. I made a code but I have to change it. These are the requirements for the program code Safe entry No magic numbers No global variables File management must be in a separate c-file - I HAVEN'T DONE THIS AND I NEED HELP All standard header files, type declarations, function prototypes etc. must be included a custom header file - I HAVEN'T DONE THIS EITHER Functions must not be too long

and when the user chooses to quit "exit", the register must be written to a file - i haven't done this

So basically I need to change the code so that it fits the requirements

#include

#define NUMBEROF_PEOPLE 10
