China DOS Union

Write a number guessing game. I don't know if anyone has played it. There is this game on the home phone, and I've played it many times. I'm also writing one myself, 7788, not perfected yet. I want to see if everyone has better ideas.

In the forum, those who feel there are no challenging experts can come out and discuss. Thanks.

Rules:

1. The game will randomly obtain a four-digit number without repeated digits from 0-9 at the beginning (the first digit can be 0)

2. The player first makes a guess, entering a four-digit number without repeated digits from 0-9

3. Compare the number obtained at the beginning of the game with the number entered by the player:

If one digit has the exact same number and position, set flag A1

If one digit has a matching number but wrong position, set flag B1

If the number and position are both mismatched, set flag B0

The exact match of number and position only sets flag A, regardless of B

For example: The answer is 4690. If I guess 0679, then the prompt is A1B2

If the prompt is A0B0, it means the guessed number does not appear at all in the answer

If the prompt is A0B4, it means the guessed number matches exactly but all positions are wrong

A4B0 is the correct answer.

4. Only 10 chances

General idea:

* Must verify the random answer

Verify if the randomly obtained number is four digits, and if each digit has repetition

* Must verify the player's input specification

Verify if the player's input is pure digits, if there is repetition, if it is 4 digits, otherwise give corresponding prompt and jump back to re-enter

* Record historical records

What the user entered for the first time, what the prompt was, must be displayed for reference when guessing the second time

* Record the number of uses

How many times have been guessed, how many times are left, displayed together with the historical records

* Must have a chance to play again

After the player uses up 10 times and hasn't guessed it, there must be a chance to play again, or if guessed correctly at once, there must be a chance to play again

The final answer is in posts 7, 9, 11, 16

I'm in a cold sweat``Why is no one researching it``

This is quite interesting;
Just been quite busy these days and haven't had time;

During the National Day holiday, I will definitely write it out and post it;

There was someone who wrote a number guessing game a long time ago, and it can be modified a bit on that basis.

I wrote a C language version before. I'll convert it to a batch file when I have time.

re bjsh:
Looking forward to the moderator's ideas yo````

re vkill:

There are people who have written it, but it's completely different, a lot different. That game is quite fake
The one I'm talking about is a game that really exists in my home fixed-line phone.
Some necessary verifications I mentioned are also distinguished from the one you mentioned.

re HAT:

Post the code here

The landlord is talking about this game, right?
http://www.cn-dos.net/forum/viewthread.php?tid=32554

re qzwqzw:

Read your post. "The anti-guessing is too slow, waited for a long time."

In fact, the actual existing number guessing game has 10 guesses, not 8.

I tested your release 1 version, and the problems I encountered are also posted in your post. Go check it yourself.

It feels like your code is quite a lot...

dosmania：
I admit that the guessing algorithm was indeed a bit shoddy
After all, it was just an R1 in my spare time

Unfortunately, no one was interested in it at that time
No discussion atmosphere was formed
Later, I also lost interest in this aspect

If you have a new algorithm, just post it out
Maybe it will rekindle my interest
------------------------------------------------------
As for the issue of guessing 8 times or 10 times
I don't think it's a problem
I originally set it to 10 times
Later, it was changed to 8 times because of the display layout and log reasons

To be honest
Among the games of this kind I have come into contact with
Those for game consoles and TVs have no limit on the number of times
For video recorders, it's limited to 8 times, and it doesn't use numbers 9 and 0
There are many varieties for computers

An excellent guessing algorithm
The exhaustive algorithm should be the one with the least number of times
But it's not the most efficient
The average number of guessing times should be less than 6 times
Setting 8 times can also be considered medium difficulty
------------------------------------------------------

"Feels like you have a lot of code``` "
I don't understand, can you explain it?

Hehe``jmz573515 is amazing, VBS interactivity is N good
if len(n)<>4 Oh``simply can't compare嘛```VBS this one solves the digit problem``
I wonder if jmz573515 has considered the repetition possibility of s1 s2 s3 s4```?

re s11ss:
Your code also fully meets the requirements```I don't know which ones you verified for random number repetition``

dosmania:
if len(n)<>4 靠``根本不能比嘛```VBS这个就搞定了位数``
I don't know what you mean by "can't compare", I think it can be limited to 4 digits??

I don't know if jmz573515 has considered the possibility of repetition of s1 s2 s3 s4...?

What do you mean by the possibility of repetition? (Do you mean how likely it is? Or whether it is possible to repeat?)
Here I only considered the possibility of repetition, so I made a judgment. If there is repetition, I generate a random number again. I didn't consider how likely it is, maybe it's not efficient...)

Random number repetition?
I don't understand your specific meaning.

Anyway, my code is to make the 4-digit numbers of the random number not repeat. As for whether the random numbers repeat among themselves, I didn't control it, but there doesn't seem to be a requirement in the question, right?
