Question

C++ language

You will create a Hangman class.
Possible private member variables:
int numOfCharacters; //for the secret word
char * secretWord;
char *guessedWord;

public:

//please create related constructors, getters, setters,constructor()

constructor()

You will need to initialize all member variables including the two dynamic variables.

destructor()

Please deallocate/freeup(delete) the two dynamic arrays memories.

guessALetter(char letter)

1.the function will check if the letter guessed is included in the word.

2. display the guessed word with related field(s) filled if the letter guessed matches the some of the letters of the word

gameResult()

1. Display how many times guessed so far

2. Display how many times with the wrong letter guessed3. Display "you win" if all letters are filled in the guess word4. Display "you lost" if the times of guessing the wrong letter reaches 6 (Note: 6 body parts - head, body, left arm, right arm, left leg, right leg)

main()

Instantiate an object of Hangman.Ask the host: how many letters in the guess word.

Ask the host: what is the guess word?

Design a loop for the player to play the guess game

1. The loop should exit if the number of wrong guess reaches 6

2. inside the loop, there should be a condition to allow the player to exit, say "Do you want to continue playing (y|n)?". If the user chooses 'n', exit the loop.

3. Inside the loop, you may do some function chaining calls, something like:

obj.guessALetter(guessLetter).gameResult()

Copy Pastable Code :

#include<bits/stdc++.h>

using namespace std;

class Hangman

int numOfCharacters;
char *secretWord; //to store secret word
char *guessedWord; //to store current guessed word. will have - for unguessed letters

public :

return *this; //returns the object this function was called on
}

int gameResult()
{

cout<<"\nYou Win\n";
return numOfCharacters;

if(wrongGuesses == 6) //if wrong guesses limit has been reached

return 0;
}
cout<<"\nTotal guesses till now : "<<guesses<<endl;
cout<<"Wrong guesses till now : "<<wrongGuesses<<endl;

}

int getWrongGuesses() //getter

};

int main()

Hangman h(l, word);

char ch = 'y';
char g;

//loop till wrong guesses are less than limit 6
while(h.getWrongGuesses() < 6)
{
cout<<"\nTo Player : Do you want to keep playing (y|n) : ";
cin>>ch;

if(ch == 'n')
break;

cout<<"\nGuess a letter : ";
cin>>g;

//if user wins exit
if( h.guessALetter(g).gameResult() == h.getNumOfCharacters())

}
}
return 0;
}

Hope this helped!
