Design Hangman

 

Hangman is a paper and pencil guessing game for two or more players. One player thinks of a word, phrase or sentence and the other tries to guess it by suggesting letters or numbers, within a certain number of guesses.

below is my steps of design hangman:

1. Start game
2. Generate a guess word from Word List
3. Print "_ _ _ _ _ " indicate how many characters in the guess word "pizza"
4. Player type in guess character "z" or "Z" both to lowercase
5. Server return whether the "?" is in the "pizza"

    a. Add "z" into the guessed pool.

    b. If correct, print all characters in the process word "_ _ z z _"
    c. If wrong, draw body, guess cnt++;
    d. Repeat 4
6. If player guessed process word == guess word, print "You Win!"
7. If guess cnt > max guesscnt, draw body, print "You Lose…"

 

my very simple C++ version. 

#include "leetcode.h"

class Hangman {
public:
    Hangman() {
        srand(time(nullptr));
        theWord = wordList[rand()%wordList.size()];
        process.append(theWord.size(), '*');
        showL(process);
        step = 0;
    }

    int guess(const char guessed) {
        char c = tolower(guessed);
        if (checkProcess(c)) {
            showL("already guessed");
            return -1;
        }
        used.insert(c);
        vector<int> idx = checkTheWord(c);
        if (!idx.empty()) {
            updateProcess(idx);
            showL(process);
        } else {
            step++;
            updateBody(step);
            if (step >= maxGuess) {
                showL("you lose!");
                showL(theWord);
                return  0;
            }
        }
        if (checkWin()) {
            showL("you win");
            return 1;
        }
        showV(used);
        return -1;
    }

private:
    vector<string> wordList = {"pizza", "movie", "banana", "hangman"};
    const int maxGuess = 6;
    int step;
    string theWord;
    string process;
    set<char> used;
    void updateBody(int step) {
        showL("wrong guess ", step, " times.");
    }
    void updateProcess(const vector<int>& idx) {
        for(auto i : idx) {
            process[i] = theWord[i];
        }
    }
    bool checkProcess(const char c) {
        if (process.empty()) return false;
        for(auto s : used) {
            if (s == c) return true;
        }
        return false;
    }
    vector<int> checkTheWord(const char c) {
        vector<int> ret;
        for(int i = 0; i < theWord.size(); i++) {
            if (theWord[i] == c) ret.push_back(i);
        }
        return ret;
    }
    bool checkWin() {
        return process == theWord;
    }
};

int main() {
    Hangman hm;
    while(1) {
        string s;
        cin >> s;
        if (hm.guess(s[0]) != -1) break;
    }
    showL("Game Over");
}
