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()
{

/* ==============================================================================================
********************************************MAIN_FUNCTION***************************************
================================================================================================*/

    //_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;

    //Account-1
    accounts[0].setName("Muhib Arshad");
    accounts[0].calculateUserName();
    accounts[0].setPin(defaultPins[0]);
    accounts[0].setSize(5);
    accounts[0].setMovementsAddress(movementsAcc0);
    accounts[0].calculateTotalBalance();
    accounts[0].calculateTotalIncome();
    accounts[0].calculateTotalOutcome();
    accounts[0].calculateTotalInterest();

    //Account-2
    accounts[1].setName("Ali Abdullah");
    accounts[1].calculateUserName();
    accounts[1].setPin(defaultPins[1]);
    accounts[1].setSize(5);
    accounts[1].setMovementsAddress(movementsAcc1);
    accounts[1].calculateTotalBalance();
    accounts[1].calculateTotalIncome();
    accounts[1].calculateTotalOutcome();
    accounts[1].calculateTotalInterest();

    //Account-3
    accounts[2].setName("Bilal Sharafat");
    accounts[2].calculateUserName();
    accounts[2].setPin(defaultPins[2]);
    accounts[2].setSize(5);
    accounts[2].setMovementsAddress(movementsAcc2);
    accounts[2].calculateTotalBalance();
    accounts[2].calculateTotalIncome();
    accounts[2].calculateTotalOutcome();
    accounts[2].calculateTotalInterest();

    //BRAIN_AND_HEART_OF_SBL
    SIGN_IN_OR_SIGN_UP(accounts, noOfAccounts, currentUser);

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

    return 0;
}

Usage

Default Accounts for login:

username	password
ma	111
aa	222
bs	333

🚀 Features:

• How to use the Dynamic Memory Allocation .
• Data hiding and Encapsultion of Classes .
• Real World Banking system .
• Login, create new account system.
• Requesting Loan ,Transfering loan system.
• Sort your movements and delete your account system.
• All input validations are done .
• No memory leakage in run-time all dynamic memory is deallocated.

🤝 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.
