2.Problem-Solving Ideas

Programming Language:Python
Because the problem is mainly object-oriented, and I systematically learned object-oriented C++ programming on the basis of Python, so I use Python to do this laboratory.

3.Design and implementation process

we need to know the keywords about C++:

auto	break	case	char	levelst	leveltinue	default	do

double	else	enum	extern	float	for	goto	if

int	long	register	return	short	signed	sizeof	stastic

struct	switch	typedef	union	unsigned	void	volatile	while

-The file is read in the specified address
-Find the keywords
-Calculate the number of keywords and the times of switches and cases
-Use pointer function probably

4.Design and implementation process

Five modules, each encapsulated in a function, and as the level of completion increases, the implementation of each functional level depends on the implementation of the previous functional level. The diagram below shows how the code is organized, the arrows indicate the level of completion, all the functions defined in the code in the flowchart.

5.Code Description

(1)create a test-file:

The code is as follows :

#include <stdio.h>  
int main(){
	int i=1;
    double j=0; 
	switch(i){  
		case 0:
			break;  
		case 1:  
		    break;  
		case 2:  
		    break;  
		default:  
		    break;  
	}  
	switch(i){  
		case 0:
			break;
		case 1:
		    break;  
		default:  
		    break;  
	}  
	if(i<0){  
		if(i<-1){}  
		else{}  
    }  
	else if(i>0){  
	    if (i>2){}  
		else if (i==2) {}  
		else if (i>1) {}  
		else {}  
	}  
	else{  
		if(j!=0){}  
		else{}  
	}  
	return 0;  
}

Summary

Through this experiment homework, I’ve gained a lot:
-How to use Github
-Planning before coding is so important
-Coding in the process of consolidating and reviewing previously learned professional courses.

The knowledge points of the document process need to be further strengthened.
