The experimental summary of compound interest calculation---software engineering

Number of lines of code	99	150/185
Workload	1.5h	2h/2.8h

The previous experiment implementation is the three functions of compound interest, from the code structure, the functional structure is very chaotic, in the fourth function, simply partition the structure after rewriting the program, took about 30 minutes, and then spent less than 20 minutes to join the function 5 and 6, remember in adding features 2 and 3 o'clock, due to the code structure confusion, It took more than 30 minutes.

In addition, after the completion of function 6, and then re-added an interface for the program, it took about 1 hours, the final code and running results: http://www.cnblogs.com/wucanlong/p/5288526.html

After this experiment, I learned more about the importance of a program of software engineering, and also solved the doubts that I saw in class why those big projects failed because of the lack of software engineering.
