Because the epidemic can only watch online classes at home. After learning C language for a few days, I plan to find a project. Today is the third day of this project. If you want to see the previous content, you can go to my same column to find it
Project: imperial concubine selection system
Six modules:
1. Imperial concubine selection - complete
Enter the name of a new concubine, add a new concubine, and then reduce the favorability of other concubines by 10 points
2. Turn over the favor - complete
Enter a concubine's name, turn over the card to favor her, increase her favorability by 10 points, and reduce other concubines' favorability by 10 points
3. Go to hell - Finish
Enter the name of a concubine, delete a concubine, and then all the other concubines will be spoiled by 10 points. If there is no one, it will show a false alarm
4. Where's my concubine - Finish
Find the concubine, input the name of the concubine and display the basic information. The selected concubine's favor degree is increased by 10 points. The other concubines' favor degree is decreased by 10 points
5. Patrol the harem - complete
Patrol the rear palace and display all the information about the concubines in the palace
6. Rules of the game - complete
1. If there are three concubines with a pet degree below 50, there will be a riot, and the game is over
2. If someone's favor reaches 100, suppress the harem and the game is over
On the third day, we basically finished the qualified project today. Why is it basic? There are still some small problems to be solved. OK, let's talk less nonsense. The pits and problems we encountered today will be placed below. The complete code is at the end
1. Rules of the game
In fact, this module only writes 10 minutes in total, which is very fast. Here is the code. There are two functions. One function judges a rule, and then performs and calculates the return value to the initial while loop condition
//Judgment function, return 0 in case of failure, otherwise 1 //Do not put the complete code. Need to look at the last int judege_1(concu *ptca, int *num); int judege_2(concu *ptca, int *num); int c, d; //Control, cycle control interface while (d)//d is the cyclic condition {.... switch{} d = judege_1(p, num) && judege_2(p, num);//!!! if (d == 0) { printf("Harem rebellion,Game failure!"); printf("Enter any key to exit.....\n"); scanf("%d", &c); } }
2. Select the imperial concubine to prevent name repetition
When I did this, I didn't consider the problem of adding the same name repeatedly. I knew that I had chosen two "concubines" with the same name in succession. My method was to add another layer of judgment before selecting concubines and increasing or decreasing the degree of favor. If I found the same name, I would directly exit the function. Although it was a little tedious, there was no way
Here is the implementation code
for (int i = 0; i < n + 1; i++) { if (strcmp(p->name, ch) == 0)//P is an array, pointer, array, structure { printf("Emperor,%s It's already in the palace!\n", ch); return 0;//Exit the function directly with return } p++; } //Judge whether it is in the palace concu *p = ptca; int a_count = 0; //Different name Feizi counter for (int i = 0; i < n; i++) { // printf("%s --- %s\n", p->name, a_name); if (strcmp(p->name, a_name) != 0) { a_count++; } // printf("%d\n", a_count); p++; } if (a_count == n) { printf(" %s Not yet in the palace...\n", a_name); return 0; }
In fact, the above work was done this morning, but it has been a bit annoying. In the process of solving the problem, I found that if I want to modify it, I need to make a big difference to the previous code. In this project, it's good that I use the variable name uniformly, so I just changed the return type of each subfunction and added a judgment, but I still feel dissatisfied, This project has 420 lines of comments in total, which is not small or small, but the logic is simple, so it can be seen how important it is to conceive before carrying out medium and large-scale projects, and how important it is to realize pseudo code!! don't rush up to write code like me, it's a lesson to learn, continue to add oil! Ollie gives!
