Welcome to BANKIST APPLICATION 👋

Bankist application in C++ by using DYNAMIC MEMPRY ALLOCATION and OBJECT_ORIENTED_PROGRAMMING concepts. Its main features are login system, user authentication ,create a new account , requesting loan , transfer money, sort your movements , currency converter , delete your account and log out system .

✨ Demo

Bankist project main feature is abstraction and data-encapsulation.Main contain only default accounts data, memory allocation and deallocation and one executed external function.

Example of Abstraction and encapsulation see main.cpp:

#include"_SBL_Features.h"

int main()
{

    //_ALLOCATION
    int noOfAccounts = 3;
    int *defaultPins = new int[noOfAccounts]{111, 222, 333};
    double *movementsAcc0 = new double[5]{2000, 1000, -500, 20000, -6000};
    double *movementsAcc1 = new double[5]{5000, -2000, 10000, 5000, -8000};
    double *movementsAcc2 = new double[5]{8000, 10000, 4000, -12000, -1000};

    //RUNTIME_INFORMATION
    account *accounts = new account[noOfAccounts];
    account currentUser;

    accounts[2].calculateTotalBalance();

    //_DEALLOCATION
    delete[] movementsAcc0;
    movementsAcc0 = nullptr;
    delete[] movementsAcc1;
    movementsAcc0 = nullptr;
    delete[] movementsAcc2;
    movementsAcc0 = nullptr;
    delete[] accounts;
    accounts = nullptr;

    return 0;
}

🤝 Contributing

Feel Free to contribute. If you want to add some features and resolve any issues then just fork the repository. To want to change the code only in the one main.cpp file then create pull-request to the master branch. I will review it and then i merge it to the branch. And same for the main branch also.
