I. Customer needs
Completed requirements:
1. Customer said: Help me develop a compound interest calculation software.
2. If according to simple interest calculation, how much is the principal and interest?
3. If a pension of $3 million is to be raised after 30, the average annual return is 3%, what is the amount of principal that must be invested now?
4. Interest rate is so low, compounding profits are so strong, if take 1 million yuan to buy annual rate of return 10% of the stock, if all smooth, too long, 1 million yuan becomes 2 million yuan?
5. If I want to turn $1 million into $2 million within 10 years, how much should I find the investment tool to help me achieve my goals? If you want to double the principal after 5 years, how much should the rate of return be at least?
6. If the savings of $30,000 are to be invested annually, with a return of 3% per annum, and then a new round of investment in these Benli and annuities, what will the total value of assets be after 30 years? What if we switch to 3000 a month?
New requirements:
1. To pursue benefits and to face unpredictable financial investment risks, "you cannot put eggs in the same basket", so it is necessary to make a portfolio investment.
The above calculations and comparisons can help customers make investment decisions.
Customer: So can you help me to record a different type of investment, and dynamically show the current value of money?

Six. Results
Seven. Harvesting and sentiment
at first do not know how the teacher assigned to understand the task, and later in the classmate help to understand some, because I and peer level is not good, can only use C language to write, and C language is not good, Java is also more difficult to achieve, but later we will go into the effort to achieve Java version, There are also many difficulties in writing the C language version, such as data storage and file reading and writing.
Teamwork is more efficient than a person's work, and the team is able to help people with poor abilities, so we have to use good pairing.
PS: have already written a good release, the results after the refresh of nothing, but also rewrite, now all timed out, ah ah ah ah ah yes
