2.Description of problem-solving ideas.

For the questions raised by the topic, I thought that the language to be used was c++, because this programming language was learned last semester, and it was faster to review.
For a series of requirements required by the topic, I think the first thing to do is to realize the function of reading files. After implementation, it is obvious that there will be a lot of symbols in the code. Before we identify the key words in the code, we must extract the non symbolic part of the code.

Level 1

is obvious. Compare each word extracted from the code with 32 keyword arrays and count them.

Level 2

find switches first, and then calculate the number of cases until the end of traversal or find the next switch. If found, repeat the previous steps.

Level 3and level 4

judge the nesting relationship according to the sequence of code if and else

3.Design and implementation process.

7.Summarize

I learned a lot from this experiment. For example, I have learned a lot from the analysis and evaluation before the program, how to use csdn to write a blog, and how to iterate versions. Thank you for software engineering! Experience the four points of happiness!
