Question 1 (20 Marks)
Overview
As a common household appliance for refrigeration and heating, air conditioners are replaced by about 20 million units in China every year. In the process of air conditioning sales, customers comprehensively consider the brand, power, noise, star level, sales volume, price, etc. You are expected to write script to read data from 'Air_condition.csv' file and complete the following tasks using R functions.
Tasks
- Read data from the 'Air_condition.csv' file, and assigns each data to a different variable. (4 marks)
- Count the sales volume of each brand. (4 marks)
- Give the product quantity of each brand. (4 marks)
- Calculate the five brands with the highest star level. (4 marks)
- Find out the factors most relevant to sales volume, in terms of brand, power, noise, star level and price. (4 marks)
Question 2 (80 Marks)
Overview
The purpose of this task is to gain experience in C++ programming and develop software development skills. You are expected to write a C++ program to develop a bank system. As a financial system in daily life, banks have good account management and savings management capabilities. The basic operations of the system include the following functions:
- AccountCreation function : Create a bank account number, including ID, name and password.
- AccountDelete function : The account can be deleted after login is successful.
- AcountQuery function : After successful login, you can query the amount of the account.
- AcountBalance function : After successful login, you can report the balance of the account.
- MoneyDeposit function : After successful login, you can deposit your money.
- MoneyWithdraw function : After successful login, you can withdraw money from your account.
- Quit function : Exit the system.
Tasks
You are required to use the Internet resources to learn the detailed rules of the bank system, and use the C ++ programming language to develop a bank system yourself.
