c++ is not pure object oriented and it is platform dependent
and doesn't support GUI

This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.

Objective The objective of this problem is to test the understanding of Object-Oriented Programming (OOP) concepts, in particular, on encapsulation. Problem Description Create a program for managing customer’s bank accounts. A bank customer can do the following operations: 1. Create a new bank account with an initial balance. 2. Deposit money into his/her account. 3. Withdraw money from his/her account. For this operation, you need to output “Transaction successful” if the intended amount of money can be withdrawn, otherwise output “Transaction unsuccessful” and no money will be withdrawn from his/her account. Input The input contains several operations and is terminated by “0”. The operations will be “Create name amount”, “Deposit name amount”, or “Withdraw name amount”, where name is the customer’s name and amount is an integer indicating the amount of money. There will be at most 100 bank accounts and they are all created on the first month when the bank is opening. You may assume that all account holders have unique names and the names consist of only a single word. Output The output contains the transaction result of withdrawal operations and the final balance of all customers after some withdrawal and deposit operations (same order as the input). Sample Input Create Billy 2500 Create Charlie 1000 Create John 100 Withdraw Charlie 500 Deposit John 899 Withdraw Charlie 1000 0
