Question & Answer: This programming projects asks you to develop a hangman game which has the following characteristics: IN C++…..

Solution: See the code below:

#include <iostream>
#include <fstream>
#include <cstdlib>
#include <algorithm>
#include <cstring>

using namespace std;

int main() {
char choice = ‘y’; //choice whether to continue or not
string wordlist_path = “./”; //path to file containing words. change it accordingly.
string wordlist_filename = “wordlist.txt”; //name of file containing words. change it accordingly.
string path = wordlist_path + wordlist_filename; //full path to file

ifstream infile(path.c_str()); //handle for file
//check if file can be opened or read.
if (!infile) {
cerr << “Error! Cannot open or read file. Aborting…” << endl;
return EXIT_FAILURE;
}
string *words; //array to store words
int num_words; //number of words in file
//count words in file
num_words = count(std::istreambuf_iterator<char>(infile),
std::istreambuf_iterator<char>(), ‘n’) + 1;
//cout<<num_words<<endl;
words = new string[num_words]; //allocate array for words
string line;
//set file stream again to first line
infile.clear();
infile.seekg(0, ios::beg);
int i = 0; //counter variable

//read words into array from file
while (getline(infile, line)) {
words[i] = line;
i++;
}

string secret_word = “”; //secret word
int secret_word_index; //location of secret word in array

//loop to play hangman game
while (choice == ‘y’) {
secret_word_index = (int) (rand() % num_words + 1); //generate a random number
secret_word = words[secret_word_index]; //set secret word
//cout<<secret_word<<endl;
int chars_to_guess = strlen(secret_word.c_str()); //number of character to guess
//cout<<chars_to_guess<<endl;
//display gallows
cout << “t___________” << endl;
cout << “t|” << endl;
cout << “t|” << endl;
cout << “t|” << endl;
cout << “_______________” << endl;
cout << “Word:”;
for (int i = 1; i <= chars_to_guess; i++) {
cout << ” _ “;
}
cout << endl;
int max_tries = 8; //maximum number of tries
char guess;
int position_to_guess = 0;
int num_incorrect_guess = 0;
char *guessed_chars = new char[chars_to_guess];
//loop to perform guesses
for (int i = 1; i <= max_tries; i++) {
//if all characters guessed properly
if (chars_to_guess == 0) {
cout << “Bravo! You guessed the word correctly.” << endl;
break;
}
//Enter character to guess
cout << “Enter a char:”;
cin >> guess;
//check character being guessed
if (guess == secret_word.at(position_to_guess)) {
//display latest status
guessed_chars[position_to_guess] = guess;
for (int i = 0; i <= position_to_guess; i++) {
cout << guessed_chars[i] << ” “;
}
chars_to_guess–;
position_to_guess++;
for (int i = 1; i <= chars_to_guess; i++) {
cout << ” _ “;
}
cout << endl;
} else //if guessed incorrectly
{
cout << “Incorrect guess:” << guess << endl;
num_incorrect_guess++;
//display state of gallows
if (num_incorrect_guess == max_tries) {
cout << “Limit reached!” << endl;
break;
}
cout << “t___________” << endl;
for (int i = 1; i <= num_incorrect_guess; i++) {
cout << “t|()” << endl;
}
cout << “t|” << endl;
cout << “t|” << endl;
cout << “_______________” << endl;
}
}
cout << “Do you wish to continue?(y/n)”;
cin >> choice;
}
infile.close(); //closes file
delete words; //delete words array
return 0;
}

Sample wordlist:

————————————————–

hello
father
mother
sun
son
complete
today
welcome
meet
country
county
google
apple
internet

Output:

————————————————
