Simulation of the Banks in the process of using the ATM interface and the user interaction process, implement query bank card balance, withdrawals, change passwords, exit the system functions, such as
2. Functional requirements:
Up to three times (1) card number, password, or exit the system directly,
(2) withdrawal function: the amount by the card balance, machine single maximum withdrawal sum and the current remaining amount limit,
(3) the query function: balance of query functions,
(4) change password: password change function, the password should have two validation,
(5) card lock function: realize the function of the card is locked,
(6) card function: exit system function,
3, the solution of the problem:
According to the system functional requirements, problem solving can be divided into the following steps:
(1) the application of system analysis, the establishment of function module diagram of this system, and the interface of the organization and design;
(2) analysis of each entity in the system and the relationship between them;
(3) according to the problem description, design system of class hierarchy;
(4) to complete the description of the various classes in class hierarchy;
(5) to complete each member function definition in the class;
(6) complete system application module;
(7) function debugging;
(8) to complete the system summary report,
