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 #include #include #include #define STR_LANGD 30 #define VEHICLE 10 #define NUMBEROF_PEOPLE 10 typedef struct { char name[STR_LANGD]; int age; } Person; typedef struct { Person person; char model[STR_LANGD]; char carbrand[STR_LANGD]; char registrationnumber[STR_LANGD]; } Vehicle; void initVehicle(Vehicle myVehicle[]) { int i; for (i = 0; i < VEHICLE; i++) { myVehicle[i].person.age = 0; } } int menu() { int choice = 0; printf ("1.

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
