2.Description of problem-solving ideas

In this lab, I decided to test the code in Python language. The first thing I’m going to do is use Python to filter out the symbols that I don’t want in the code I’m testing.[“+”, “-”, “*”, “/”, “<”, “<=”, “>”, “>=”, “=”, “==”, “!=”, “;”, “(”, “)”, “^”, “,”, “”“, “'”, “#”, “&”,&&”, “|”, “||”, “%”, “~”, “<<”, “>>”, “[”, “]”, “{”, “}”, “\”, “.”, “:”, “!”] ，so I will remove them before my testing.The next thing I need to do is write the code I’m going to test to a file and let Python read it, which makes it easier for me.After Python read the file, I removed all the symbols I didn’t need and used Python’s split function to change the article into English words, which was more convenient for my later code writing.For the first question, it is easy to collect all the keywords in C++, put them into a list, and then match the previously divided English words. In this way, it is easy to read out the total number of C++ keywords in the code.The same is true for the second problem, and a similar approach can be used.
For the third problem, I’m going to create a list, put the words I want in it, and have them go to the list in order. This can be solved by reusing the logic code.
I thought about the fourth question for a long time, and then I came up with the method of list deletion, as long as I can find a loop in the constant reading, delete the duplicate to find the if-elseif-else structure
Instead of a single pass, I think the parser should be designed as a subroutine. Whenever the parser needs a word symbol, it passes an input string to the parser, and the parser can analyze the words in the input string.

3.Design and implementation process.

4.Code description.

def get_file():#get the file we want to getf = open(filename,'r',encoding='UTF-8')file = f.read()#Only leave the content we want to leavesymbol_list = ["+", "-", "*", "/", "<", "<=", ">", ">=", "=", "==","!=", ";", "(", ")", "^", ",", "\"", "\'", "#", "&","&&", "|", "||", "%", "~", "<<", ">>", "[", "]", "{","}", "\\", ".", ":", "!"]  #the symbols in C++for i in symbol_list:file = file.replace(i," ")#replace unwanted symbolsf.close()return file

In this code,we can read from the test code and transform it into a file which is convinent for us to work on the following steps.

And this is the result.It is expected to what I think.Very great!!!
