This is the code I used:

#include <stdio.h>
#include <string.h>

#define MAX_ACCOUNTS 255

typedef struct
{
    unsigned int id;
    char account_creation_date [10];
    char first_name [255];
    char last_name [255];
    char country_code [2];
    unsigned int iban;
    char password [255];
    double balance;
} account;

account accounts_db[MAX_ACCOUNTS];
unsigned int accounts_created = 0;

account get_account_id (unsigned int id)
{
    int i = 0;
    while(i < MAX_ACCOUNTS)
    {
        if(accounts_db[i].id == id)
        {
            return accounts_db[i];
        }
        i++;
    }
    account account;
    account.id = -1;
    return account;
}

void create_account(char first_name [255], char last_name [255], char password [255], char country_code [2])
{
    account new_account;
    new_account.id = accounts_created;
    strcpy(new_account.first_name, first_name);
    strcpy(new_account.last_name, last_name);
    strcpy(new_account.password, password);
    strcpy(new_account.country_code, country_code);
    strcpy(new_account.account_creation_date, "");
    new_account.balance = 0.0;
    new_account.iban = 0;
    accounts_db[accounts_created] = new_account;
    accounts_created++;
}

int main()
{
    char first_name [255]  = "Max";
    char last_name [255] = "Mustermann";
    char country_code [2] = "DE";
    char password [255]= "password";
    create_account(first_name, last_name, password,country_code);
    account account = get_account_id(0);
    printf("Name: %s %s \n", account.first_name, account.last_name);
    printf("Account creation date: %s\n", account.account_creation_date);
    printf("IBAN: %s %d", account.country_code, account.iban);
}```

When you run it you can see, that behind the country code of the IBAN you get the first two letters of the surename

How do you get destructor behavior in C?
