"eBank" is a simple C++ project designed as a simple Internet Banking application.
It is not linked to a database or made with a real purpose, it is made as an experiment.
- Sign up
When you start the program, you will be required to register using a 6-digit pin.
int pin_signup(){
int pinsup = 0;
std::cout << "Welcome to eBank! Please enter a 6-Digit PIN for registration: ";
std::cin >> pinsup;
while (checkdigit(pinsup) != 6){
std::cout << "You have not entered a 6-digit PIN. \n" ;
std::cout << "Please enter a 6-Digit PIN for registration: ";
std::cin >> pinsup;
}
std::cout << "Congratulations! You have successfully created your eBank account! \n";
return pinsup;
}
Checking the number of digits is done with:
int checkdigit(int pin){
return int(log10(pin) + 1);
}- Sign in
The connection to the "application" will be made using the pin with which the user registered.
bool pin_login(int pin){
int pinlogin = 0, k = 3;
std::cout << "Please enter your PIN:";
while (k){
std::cin >> pinlogin;
if (pinlogin == pin){
std::cout << "You have successfully logged in!\n";
return true;
}
else{
std::cout << "The pin is incorrect. You have " << k-1 << " more attempts:";
k--;
}
}
std::cout << "\n";
std::cout << "The account has been blocked! Please contact a bank representative for more information.";
return false;
}
- The main menu of the application
void choicemessage(){
int choice = 0;
std::cout << "*******************\n";
std::cout << "Enter your choice:\n";
std::cout << "*******************\n";
std::cout << "1. Show balance\n";
std::cout << "2. Deposit money\n";
std::cout << "3. Withdraw money\n";
std::cout << "4. Transfer money\n";
std::cout << "5. Exit\n";
}
void in_choice(int choice, double balance){
switch(choice){
case 1: showBalance(balance);
break;
case 2: deposit(balance);
break;
case 3: withdraw(balance);
break;
case 4: sendmoney(balance);
break;
}
}- Show Balance
This function is capable of showing the sum that the user has in the application.
void showBalance(double balance){
std::cout << "Your balance is: " << balance << "€\n";
Anotheroperation(balance);
}- Deposit money
This function allows you to deposit less than 100000e.
void withdraw(double balance){
int amount = 0;
std::cout << "Enter amount to be withdrawn: ";
std::cin >> amount;
if (amount > 100000)
std::cout << "For security reasons, you cannot withdraw an amount greater than or equal to 100000€ in a signle operation.\n";
else if (amount < balance)
{
balance -= amount;
std::cout << "You have successfully withdrawn " << amount << "€\n";
}
else
std::cout << "Insufficient funds.\n";
Anotheroperation(balance);
}
- Withdraw money
You can withdraw an amount of money from your current account.
For "security" reasons, you cannot withdraw an amount greater than or equal to 100000€ in a single operation.
void withdraw(double balance){
int amount = 0;
std::cout << "Enter amount to be withdrawn: ";
std::cin >> amount;
if (amount > 100000)
std::cout << "For security reasons, you cannot withdraw an amount greater than or equal to 100000€ in a single operation.\n";
else if (amount < balance)
{
balance -= amount;
std::cout << "You have successfully withdrawn " << amount << "€\n";
}
else
std::cout << "Insufficient funds.\n";
Anotheroperation(balance);
}- Transfer money
7.1. Manual Transfer - function that allows you to transfer an amount of money to an IBAN of your choice (iban.length() == 24)
void manualtransfer(double balance){
std::string iban; // ex = "RO49AAAA1B31007593840000";
int amount, choice;
std::cout << "IBAN:";
std::cin >> iban;
if (iban.length() == 24){ //RO 24
std::cout << "Amount:";
std::cin >> amount;
if (balance >= amount){
std::cout << "Your new balance will be " << balance-amount << "€. Is that okay? (0 = no, 1 = yes) ";
std::cin >> choice;
if (choice == 1){
balance = balance-amount;
std:: cout << "Thank you for the transaction.";
}
}
else {
std:: cout << "Insufficient funds.\n";
}
}
else{
std::cout << "IBAN is incorrect.";
}
Anotheroperation(balance);
}7.2. Pay bills - the function allows you to pay an invoice/insurance/others without entering the IBAN
void bills(double balance, int choice_1, int choice){
int amount;
std::string details, series;
if (choice_1 == 1){
std::cout << "Amount:";
std::cin >> amount;
if (amount > balance && amount > 0){
std::cout << "Insufficient funds.\n";
Anotheroperation(balance);
}
else {
std::cout << "Details of the transfer:";
std::cin >> details;
std::cout << "Series and policy number:";
std::cin >> series;
}
companies_database(choice, choice_1);
std::cout << "Amount: " << amount << "\n";
std::cout << "Total amount in account currency (including commissions): " << amount-(rand()%2+1) << "\n";
std::cout << "Execution date: ";
amount < 1000 ? std::cout << "As soon as possible\n" : std:: cout << "Up to 5 business days\n";
std::cout << "Details of the transfer:";
std::cout << details << "\n";
std::cout << "Series and policy number:";
std::cout << series << "\n";
int op;
std::cout << "Is that okay? (0 = no, 1 = yes)\n";
std::cin >> op;
if (op){
if (std::cin.get() == '\n')
balance-=amount;
std::cout << "Thank you for the transaction.";
}
Anotheroperation(balance);
}
