C ++ Hangman项目

Question

我的Hangman代码有问题。

这是我得到的错误：

  

错误：无法将参数'1'的'std :: __ cxx11 :: string {aka std :: __ cxx11 :: basic_string}'转换为'char'到'int checkGuess（char，std :: __ cxx11 :: string， std :: __ cxx11 :: string＆）'

从来没有真正看到过这样的错误。

这是我的代码：

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
#include <fstream>
#include <string>
#include <vector>


using namespace std;

int NUM_TRY = 15;
int checkGuess(char, string, string&);
void main_menu();
string word;

void beolvas(vector <string> &words);
void kiir   (vector <string> words);
void betolt (vector <string> words);
string message = "Play!";

int main(int argc, char *argv[])
{

vector <string> words;
string name;
string letter;
beolvas(words);
kiir(words);
betolt(words);

string hide_m(word.length(), '-');    

while(NUM_TRY != 0){
main_menu();
cout<<"\n\n\t\t\t\t" <<hide_m;
cout<<"\n\n\t\t\t\tMondj egy betut:  ";
getline(cin, letter);
if (checkGuess(letter, word, hide_m)==0)
 {
 message = "Incorrect letter!";
 NUM_TRY = NUM_TRY - 1;
 }
 if (word == hide_m);
 {
  cout<<"Congratulations, you guessed the word."<<endl;
  cout<<"\t\t\tThe word was "<<word<<endl;
  break;
 }
 if (letter == hide_m)
 {
   cout<<"Good job. You guessed a letter."<<endl;
     }
   }
 }
 void beolvas(vector <string> &words)
 {
   string sor;
   ifstream fin("words.txt");
   while(!fin.eof()){
   getline(fin, sor);
   words.push_back(sor);
  }
  fin.close();
 }

  void kiir(vector <string> words)
 {
  ofstream fout("olvasd.txt");
  srand(time(NULL));
  int n =rand() % 236;
  fout<<words[n]<<endl;
 }

  void betolt(vector <string> words)
  {
    ifstream input("olvasd.txt");
    while(!input.eof()) {
    getline(cin, word);
   }
  input.close();
   }

   int checkGuess(char guess, string secretword, string &guessword)
   {
   int i;
   int matches = 0;
   int len = secretword.length();
   for(i = 0; i < len; i++)
   {

    if(guess == guessword[i])
   {
    return 0;

  }
  if(guess == guessword[i])
   {
    guessword[i] = guess;
    matches++;
     }
    }
   return matches;
   }

   void main_menu()
    {
   system("color B");    //Light Aqua 
   system("cls");
   cout<<"\t\t\t\t\t";
   cout<<"\n\t\t\tHangman";
   cout<< "\n\t\tYou have" <<NUM_TRY <<" tries, to guess the word. ";
    cout<<"\n\n\t\t\t\t"+message;
 } 

Answer 1

checkGuess采用char类型作为第一个参数，但是您提供的letter实际上是std::string类型。该代码将无法编译。

您可以改为阅读letter[0]来获取字符串的第一个char。首先确保letter.length()大于0。
