Question
TEXT FILE IS ALREADY GIVEN, JUST NEED TO READ IN THE PROGRAM.
Learning objectives: The intent of this programing project is to allow you the opportunity to demonstrate your ability to solve problems using procedural C++ programming. This project HANG MAN will focus on file I/O and string manipulation in the implementation of the game Hangman. Program Description: In this project, you will write a C++ program that simulates playing the game Hangman. This version of the game will be limited to words with up to eight letters. The program should operate as follows: 1. The program must use a function that displays the hangman's gallows (see below). This function accepts an integer for the total number of incorrect guesses. This number will range from zero, representing the start of the game, to eight representing the end of the game. L L L L L L L L L Game Two Three Four Five Six Seven Game Start Incorrect Incorrect Incorrect Incorrect Incorrect Incorrect Incorrect Over Guess Guesses Guesses Guesses Guesses Guesses Guesses 2. Each time a game is played, the program will randomly select an unknown word from a file called words txt. Each of the thirty words in the file will be... Limited to a maximum of eight letters in length. No letter will ever appear more than once in any word. All words will be in lower case. 3. The program should then display the hangman's gallows, and a string of asterisk representing the unknown word, and a prompt for the letter to be guest.Explanation / Answer
