// First look at multi-file projects // This code is an adaptation of a live stream on pointers and structs // // Marc Chee (firstname.lastname@example.org), October 2020 // // A header file like this contains information about a some code. // It's usually enough to read this to be able to use the code // without needing to actually delve into the C file. #define MAX_NAME_LENGTH 50 #define MAX_POWER_LENGTH 50 #define MAX_NUM_POWERS 5 // This typedef declares that the type "Person" is the same as the type // "pointer to struct person". // // The actual definition of "struct person" is not in person.h (this // file), it's in person.c // // This means that you cannot directly access any of the fields of the // person struct -- e.g. "person->name" is invalid. typedef struct person *Person; // Create a person and return a pointer to them Person create_person(char name[MAX_NAME_LENGTH]); // free_person frees any memory used for a person void free_person(Person hero); // give_power will add a power to a person // It will add the string to the array of strings // called powers if the person still has // space to add powers void give_power(char power[MAX_POWER_LENGTH], Person hero); // Displays a person's information void display_person(Person hero);
