Pointers and/or functions not working correctly - c

Question

Attempting to run this code will display blank inputs for most of the fields and will be mixed up, for example the street number would be in place of first name. Not sure what's going on. Was hesitant about using stackoverflow at first but now it seems I have no choice
header file:
// Structure type Name declaration
struct Name {
char firstName[31];
char middleInitial[7];
char lastName[36];
};
// Structure type Address declaration
struct Address {
int streetNumber;
char street[41];
int apartmentNumber;
char postalCode[8];
char city[41];
};
// Structure type Numbers declaration
struct Numbers {
char cell[11];
char home[11];
char business[11];
};
// Structure type Contact declaration
struct Contact {
struct Name name;
struct Address address;
struct Numbers numbers;
};
//------------------------------------------------------
// Function Prototypes

// Get and store from standard input the values for Name
void getName(struct Name* name);
// Get and store from standard input the values for Address
void getAddress(struct Address* address);

void getNumbers(struct Numbers* numbers);

while (getchar() != '\n');
}
// Get and store from standard input the values for Name
void getName(struct Name* name) {
char option = 0;
printf("Please enter the contact's first name: ");
scanf("%31s", name[0].firstName);
clear();
printf("Do you want to enter a middle initial(s)? (y or n): ");
scanf("%c", &option);
clear();
if (option == 'y' || option == 'Y') {

clear();
}

printf("Please enter the contact's street number: ");
scanf("%d", &address[0].streetNumber);

}
// Get and store from standard input the values for Numbers
void getNumbers(struct Numbers* numbers) {
char option = 0;
printf("Do you want to enter a cell phone number? (y or n): ");
scanf("%c", &option);
clear();
if (option == 'y' || option == 'Y') {
printf("Please enter the contact's cell phone number: ");
scanf("%11s", numbers[0].cell);
clear();
}
printf("Do you want to enter a home phone number? (y or n): ");
scanf("%c", &option);
clear();
if (option == 'y' || option == 'Y') {
printf("Please enter the contact's home phone number: ");
scanf("%11s", numbers[0].home);
clear();
}
printf("Do you want to enter a business phone number? (y or n): ");
scanf("%c", &option);
clear();
if (option == 'y' || option == 'Y') {
printf("Please enter the contact's business phone number: ");
scanf("%11s", numbers[0].business);
clear();
}
}
my main program:
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include "contacts.h"
int main(void)
{
// Declare variables:
struct Contact contact[] = {{0}};
// Display the title
printf("Contact Management System\n");
printf("-------------------------\n");
// Call the Contact function getName to store the values for the Name member
getName(contact);
// Call the Contact function getAddress to store the values for the Address member
getAddress(contact);
// Call the Contact function getNumbers to store the values for the Numbers member
getNumbers(contact);
// Display Contact summary details
printf("\n");
printf("Contact Details\n");
printf("===============\n");
printf("Name Details\n");
printf("------------\n");
printf("First name: %s\n", contact[0].name.firstName);
printf("Middle initial(s): %s\n", contact[0].name.middleInitial);
printf("Last name: %s\n", contact[0].name.lastName);
printf("\n");
printf("Address Details\n");
printf("--------------\n");
printf("Street number: %d\n", contact[0].address.streetNumber);
printf("Street name: %s\n", contact[0].address.street);
printf("Apartment: %d\n", contact[0].address.apartmentNumber);
printf("Postal code: %s\n", contact[0].address.postalCode);
printf("City: %s\n", contact[0].address.city);
printf("\n");
printf("Phone Numbers\n");
printf("-------------\n");
printf("Cell phone number: %s\n", contact[0].numbers.cell);
printf("Home phone number: %s\n", contact[0].numbers.home);
printf("Business phone number: %s\n", contact[0].numbers.business);
printf("\n");
// Display Completion Message
printf("Structure test for Contact using functions done!\n");
return 0;
}
any help would be greatly appreciated, thanks

Answer 1

you have an error in main when calling your functions
getName(contact);
getAddress(contact);
getNumbers(contact);
your passing a contact struct while they wait for other structure types.
void getName(struct Name* name);
void getAddress(struct Address* address);
void getNumbers(struct Numbers* numbers);
try to correct this with
getName(&contact->name);
getAddress(&contact->address);
getNumbers(&contact->numbers);
