Word Guessing Game C++

Question

I'm new to programming, so I created number guessing game which worked perfectly but I can't seem to finish with the word guessing code. My goal is to print "Congratulations" when the guessed string is correct, but I tried many ways and I still can't make it work.

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

using namespace std;

int main()
{
    srand(time(0));
    int i;
    const string wordList[17] = { "television",
        "computer", "keyboard", "laptop", "mouse", "phone", "headphones",
        "screen", "camera", "sound", "science", "programming", 
        "entertainment",
        "graphics", "intelligent", "memory", "remote" };

    string word = wordList[rand() % 17];

    for(i = 0; i < word.length(); i++)
    {
        if(word[i] == 'a' || word[i] == 'e' || word[i] == 'i' ||
           word[i] == 'o' || word[i] == 'u')
        {
            word[i] = '_';
        }
    }

    cout << word << endl;
    int n=0;
    string x;
    do
    {
        n++;
        cin >> x;
    }
    while(x!=word[i]);
    cout<<"Congratulations! You guessed the word!";

    return 0;
}

I'd say most of your problems come down to this line:

while(x!=word[i]);

As the comments suggest, word is your modified word, not the word list. But also, i is the wrong index. So save the word index you chose earlier:

size_t wordIndex = rand() % 17;
string word = wordList[wordIndex];

Then change your do loop condition:

while (x != wordList[wordIndex]);

I'd also recommend that you don't use using namespace std; .

You could argue about the use of rand() , but it might not be worth it. Just be aware that rand() has shortcomings and better alternatives exist.
