Console Bank Application

Z Hussain

I know C# and can try doing it but I need someone's explanation to carry out this task, Can some one please help me in coding a solution that can perform the following workflows through a console application (accessed via the command line):

-Create a new account

-Login

-Record a deposit

-Record a withdrawal

-Check balance

-See transaction history

-Log out

C# is preferred but not required. Use whatever frameworks/libraries you wish, and just make sure they are included or available via NuGet/npm/etc. Please use a temporary memory store (local cache) instead of creating an actual database.

Hi,

I am trying to build similar app. Can someone please guide me how we can store data instead of an actual Database? Little bit of sample code would be more helpful please. Data needs to be stored for each and every action.

It seems to me that this is some learning assignment/study question hence it does not need any actual bank interaction, otherwise in an actual application you need to contact a banking service provider which has APIs which you can call to do banking transactions.

as in your case, you can achieve by following:

1) show the user option in console by message, e.g. press 1 for login, press 2 for new account

2) take user input using read key and if 1 or 2 do further task accordingly, e.g. for login as user name and password, for new account as to enter new user name, etc.

3) same way for all other transactions

4) store data in variables, arrays, lists, and based on user input show result.

something like:
using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            double balance = 0;

            Console.WriteLine("Press 1 for deposit, press 2 for withdrawal, 3 for balance: ");
            var input = Console.ReadKey();

            if (input.KeyChar == '1')
            {
                //logic for deposit here
                Console.WriteLine("Enter deposit amount: ");
                var deposit = Console.ReadLine();
                //convert deposit to double and add to balance.
            }
            else if (input.KeyChar == '2')
            {
                //logic for deposit here
            }
            else
            {
                //invalid input
            }
        }
    }
}
