Question

c++ program need help.

write a program to create a hangman game with the algorithm used below(not with different algorithm).It should use everything as below

{
   char guessedletters[26] = { '' }; //sets all guessed letters to null
   int guessleft = 6;
   int lenw; //length of actual word
   int guessed = 0; //if set to 1 then quit
   int i, x, xflag, winflag = 0;
   char userguess = ''; //the current letter guessed by the user
   char guessedword[20];

   //The guessedword contains the word as the user
   //knows it at the current time. So if they
   //guessed one correct letter, it will show the one
   //letter in the correct location. It is set to
   //underscores so that it shows the user which
   //letters are still missing.
   for (x = 0; x<20; ++x)
       guessedword[x] = '_';

   //The secretword is a global variable defined
   //at the top of the program. This means you
   //don't have to pass it to any other functions.
   //You don't have to use a secretword. You can
   //have an array with a bunch of secret words and
   //the computer randomly picks a word (recommended)
   //or you can have a second user enter a word.
   //Either way, leave it like this until you get
   //it working and then change it to one of the
   //above cases if you like.
   lenw = secretword.length(); //secretword is defined at top of program

                               //*ADD a WHILE LOOP here while the user has not guessed the
                               //*word AND (&&) while you still have guesses left (guessleft is above 0)
   {

       drawing(guessleft); //This draws the first hangman picture
       cout << "Guessed letters: ";
       //***Insert a for loop to print out the current list
       //***of guessed letters - that is, print out the array
       //***guessedletters
       cout << endl;

       cout << "This is what you have: " << endl;
       for (x = 0; x            cout << guessedword[x] << " ";
       cout << endl << endl;

       //***Go through the guessedword array
       //***to see if it has been completely guessed
       //*** and if so, tell user they won and break out
       //*** or else if user did not win,
       //*** make sure winflag is set back to 0
       //*** and continue on. Do it any way you like,
       //*** but winflag=1 if they guessed word and
       //*** winflag=0 if they have not.

       //***Get user guess and save it in the
       //***variable userguess

       xflag = 0;
       for (i = 0; i<26; ++i) //User has 26 tries with letters
       {
           if (userguess == guessedletters[i])
           {
               cout << endl << "You already guessed this letter." << endl;
               system("pause");
               break;
           }
           else if (guessedletters[i] == '') //this means the letter wasn't guessed yet
           {
               guessedletters[i] = userguess; //so add userguess as a guessed letter

                                           //***go through and see if the userguess is anywhere in
                                           //***secretword, and if so, update the guessedword array
                                           //***with the letter. You will also need to
                                           //***update the guessleft variable (decrement it) if
                                           //***they haven't guessed correctly. If they did guess
                                           //***a correct letter than don't decrement guessleft since
                                           //***they don't lose a try if they guessed correctly.

           }
       }

   }

   cout << endl << "Game finished..." << endl;
   if (winflag == 0)
   {
       drawing(0);
       cout << "Sorry. Better luck next time!" << endl;
   }

Explanation / Answer

Here is the solution :-

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
using namespace std;
const int MAX_TRIES=5;
int letterFill (char, string, string&);
int main ()
{
string name;
char letter;
int num_of_wrong_guesses=0;
string word;
string words[] =
{
"india",
"japan",
"nepal",
"china",
"madagascar",
"azerbaijan",
"kyrgyzstan",
"turkmenistan",
"french guiana",
"new caledonia"
};
//choose and copy a word from array of words randomly
int n=rand()% 10;
word=words[n];
// Initialize the secret word with the * character.
string unknown(word.length(),'*');
// welcome the user
cout << " Welcome to hangman!! Guess a country that comes into your mind.";
cout << " Each letter is represented by an asterisk.";
cout << " You have to type only one letter in one try.";
cout << " You have " << MAX_TRIES << " tries to try and guess the country.";
cout << " ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~";
// Loop until the guesses are used up
while (num_of_wrong_guesses < MAX_TRIES)
{
cout << " " << unknown;
cout << " Guess a letter: ";
cin >> letter;
// Fill secret word with letter if the guess is correct,
// otherwise increment the number of wrong guesses.
if (letterFill(letter, word, unknown)==0)
{
cout << endl << "Whoops! That letter isn't in there!" << endl;
num_of_wrong_guesses++;
}
else
{
cout << endl << "You found a letter! Isn't that exciting?" << endl;
}
// Tell user how many guesses has left.
cout << "You have " << MAX_TRIES - num_of_wrong_guesses;
cout << " guesses left." << endl;
// Check if user guessed the word.
if (word==unknown)
{
cout << word << endl;
cout << "Yeah! You got it!";
break;
}
}
if(num_of_wrong_guesses == MAX_TRIES)
{
cout << " Sorry, you lose...you've been hanged." << endl;
cout << "The word was : " << word << endl;
}
cin.ignore();
cin.get();
return 0;
}
/* Take a one character guess and the secret word, and fill in the
unfinished guessword. Returns number of characters matched.
Also, returns zero if the character is already guessed. */
int letterFill (char guess, string secretword, string &guessword)
{
int i;
int matches=0;
int len=secretword.length();
for (i = 0; i< len; i++)
{
// Did we already match this letter in a previous guess?
if (guess == guessword[i])
return 0;
// Is the guess in the secret word?
if (guess == secretword[i])
{
guessword[i] = guess;
matches++;
}
}
return matches;
}
