How to move other function but main function to another header file and cpp file, and add an int id that will contain with individual account information?

#include #include #include #include

using namespace std;

class Account { public: string name; double balance; Account(string n, double b) : name(n), balance(b) {} };

void displayAccountInfo(list& accounts) { for_each(accounts.begin(), accounts.end(), [](Account& account){ cout << "Name: " << account.name; cout << " Balance: " << account.balance << endl; }); }

int i = 0; list::iterator it;

for (it = accounts.begin(); it != accounts.end(); it++) { if (i == nameid) { it->balance += deposit; cout << "Deposit added successfully" << endl; return; } i++; } cout << "Account not found" << endl; }

void withdraw(list& accounts) { int nameid; double withdraw; cout << "Enter the the account id: "; cin >> nameid; cout << "Enter the withdrawal amount: "; cin >> withdraw;

int i = 0; list::iterator it;

for (it = accounts.begin(); it != accounts.end(); it++) { if (i == nameid) { if (it->balance < withdraw) { cout << "Insufficient funds" << endl; return; } it->balance -= withdraw; cout << "Withdrawal successful" << endl; return; } i++; } cout << "Account not found" << endl; }

accounts.emplace_back(name, balance); cout << "Account created successfully" << endl; }

void findAccountById(list& accounts) { int id; cout << "Enter the the account id: "; cin >> id; int i = 0; list::iterator it; for (it = accounts.begin(); it != accounts.end(); it++) { if (i == id) { cout << "ID: " << i << endl; cout << "Name: " << it->name << endl; cout << "Balance: " << it->balance << endl; return; } i++; } cout << "Account not found" << endl; }

void showTotalBalance(list& accounts) { double total = accumulate(accounts.begin(), accounts.end(), 0.0f, [](double acc, Account& account){ return acc + account.balance; }); cout << "Total in all accounts: " << total << endl; }
