如何跟踪c ++中hangman游戏中使用的字母？

Question

我正在尝试用c ++制作一个刽子手游戏，我似乎无法跟踪已经在游戏中使用过的字母。我已经包含了下面的代码，所以你可以查看它，请告诉我如何解决这个问题。

#include<iostream>
#include<cstring>
#include<cstdlib>
#include<ctime>

using namespace std;

int main(){

string words[] =
{   "artistic",
    "recreational",
    "programmer",
    "indistinct",
    "sincere",
    "pulchritude",
    "legendary",
    "scientific",
    "oblivious",
    "tomorrow"
};


string word,unknownword,wordrevelation;
   char playername[100];

   cin.getline(playername,100,'\n');
   cout << endl << endl;

   cout << endl << endl << endl;

要跟踪字母，请创建一个字符串并添加用户键入的字母。然后在每次输入后循环遍历它以查看输入之前是否已输入。如果是，则提示用户输入另一个输入。否则继续这个过程。
