Функция C++ не работает

---

Эй ребята я строю проект на c++ это в основном банковская система
две функции моего кода не работают, я не знаю почему!!
функции вывод и отображение,,
вот код

#include<iostream>
using namespace std;

struct Address{
	string stName;
	int houseNum;
};
struct Account{
	string name;
	int accnumber;
	double balance;
	Address addr;
};

void menu(); // program interface
void withdraw(Account accounts[] , int acnum , double amount);
void Create_account(int &i,Account accounts[] , Address addreses[]); 
void display(Account accounts[] , Address addreses[] , int acnum);
double deposit(double&balance , double amount);


int main(){
	
	while (true){
		
		system("color 0a");
		menu();
	
	}
	
	
}
// main Menu , program start
void menu(){
	// index of array
		int i = 0 ;
		int choice;
		Account accounts[10] ;
		Address addreses[10];
		int acnum;
		double amount;
		cout << endl;
		system("cls");
		cout << "\t\t\t --- Enter your choise --- " << endl;
		cout << endl;
		cout << "\t\t\t 1 - Create Account\n";
		cout << endl;
		cout <<"\t\t\t 2 - Deposit Money" <<endl;
		cout << endl;
		cout << "\t\t\t 3 - Withdraw Money" <<endl;
		cout << endl;
		cout << "\t\t\t 4 - Display" << endl;
		cout << endl;
		cout << "\t\t\t 5 - Exit" << endl;
		cout << endl;
		cout << "\t\t\t choice is :  ";
		cin >> choice;
		system("cls");
		switch (choice){
			case 1:
				Create_account(i, accounts , addreses);
				break;
		
			case 2:
				cout << "\t\tEnter the amount you Want to deposit :" ;
				break;
			case 3 :
				cout << "\t\tPlease enter the acc number: " ;
				cin >> acnum;
				cout << "\t\tEnter amount to withdraw : ";
				cin >> amount;
				withdraw(accounts , acnum , amount);
				break;
			case 4:
				cout << "\t\tPlease enter the acc number: " ;
				cin >> acnum;
				display(accounts , addreses , acnum);
				break;
				
				break;
			case 5:
				cout << "Good bye !!!";
				exit(0);
				break;
		}
		}
		
		
// function to Create a new account
void Create_account(int &i , Account accounts[] , Address addreses[]){
	system("cls");	
	cout << "\t\t\t --- Create New Account --- " << endl;
	cout << "\t\t Name: ";
	cin >> accounts[i].name;
	cout << "\t\t Account Number: ";
	cin >> accounts[i].accnumber;
	cout << "\t\t Balance: ";
	cin >> accounts[i].balance;
	cout << "\t\t\t --- Address Information --- " << endl;
	cout << "\t\t Streat Name: ";
	cin >> addreses[i].stName;
	cout << "\t\t House Number : ";
	cin >> addreses[i].houseNum;
	i++;
	}
void withdraw(Account accounts[] , int acnum , double amount){
	for (int i = 0; i <= 10 ;i++){
	if (accounts[i].accnumber == acnum){
		accounts[i].balance -= amount;
		cout << "\t\tDone.";
		break;
	}
	else if (i == 10 ){
		cout << "\t\tAccount Not Found !!!" << endl;
	}
}}
double deposit(double &balance , double amount){
	
}

void display(Account accounts[] , Address addreses[] , int acnum){
	for (int i = 0; i <= 10 ;i++){
	if (accounts[i].accnumber == acnum){
		cout << "\t\tName : " << accounts[i].name;
		system("PAUSE");
	
	}
}}

Что я уже пробовал:

каждая вещь и это убивает меня ):
