Lesson 8 - Person database in C - Creating persons and application menu

C and C++ The C language Dynamic memory allocation Person database in C - Creating persons and application menu

In the previous lesson, Person database in C - The linked list module, we prepared a module with a linked list for a person database program. In today's C tutorial, we're going to implement basic list functions and the application menu.

We'll implement creating a person and adding it to the list as 2 separated functions. Sometimes, we might need to add an already existing person.

Creating a person

The function for creating a person will work similarly as the function creating the list:

PERSON *create_person()
    PERSON *p_person = (PERSON *) malloc(sizeof(PERSON));
    if (p_person == NULL)
        printf("Not enough memory to create a person.\n");
    return p_person;

The function returns a pointer to the newly created structure.
