Beginning with Structs in C - c

Question

Every time I try to compile the following code I get a boatload of errors.
Does anyone see any obvious things that I overlooked with my C program. Any help would be appreciated.
The header file structures.h is also attached.
This is the structures.cc file
#include <stdio.h>
#include <string.h>
#include "structures.h"
void getOnePerson(person_t *p) {
char *name;
char *ssn;
int *year;
printf("Enter full name: ");
scanf("%s", &name);
p.name = &name;
printf("\nEnter ssn: ");
scanf("%s", &ssn);
p.ssn = &ssn;
printf("\nEnter year of birth: ");
scanf("%d", year);
p.yearOfBirth = &year;
}
void printOnePerson(person_t t1) {
char *name = t1.name;
char *ssn = t1.ssn;
int year = t1.yearOfBirth;
printf("%s", &name);
printf(":");
printf("%s", &ssn);
printf(":");
printf("%p", &year);
printf("\n");
}
void getPeople(person_t peoples[], int people) {
for (int a = 0; a < people; a++) {
getOnePerson(peoples[a]);
}
}
void printPeople(person_t peoples[], int people) {
for (int p = 0; p < people; p++) {
peoples[p];
}
}
This is the structures.h file
#include <stdio.h>
#include <string.h>
#define NAME_SIZE 80
#define SSN_SIZE 13
#define NUM_PEOPLE 10
typedef struct{
char name[NAME_SIZE];
char ssn[SSN_SIZE];
int yearOfBirth;
}person_t;
void getOnePerson(struct person_t *p);
void printOnePerson(struct person_t p);
void getPeople(struct person_t peoples[], int people);
void printPeople(struct person_t peoples[], int people);

Answer 1

Your function declarations in the header file are incorrect.
You make reference to one or more parameters of type struct person_t, but there is no such type. There is a type named person_t, so change the function prototypes to use that.
void getOnePerson(person_t *p);
void printOnePerson(person_t p);
void getPeople(person_t peoples[], int people);
void printPeople(person_t peoples[], int people);
Your get and print functions also have several issues. In both cases, you're using intermediate variables to read/write values which aren't necessary:
void getOnePerson(person_t *p) {
printf("Enter full name: ");
scanf("%s", p->name);
printf("\nEnter ssn: ");
scanf("%s", p->ssn);
printf("\nEnter year of birth: ");
scanf("%d", &p->yearOfBirth);
}
void printOnePerson(person_t t1) {
printf("%s", t1.name);
printf(":");
printf("%s", t1.ssn);
printf(":");
printf("%d", t1.yearOfBirth);
printf("\n");
}
