c++ write a hangman game that randomly generates a word and prompts the user to guess one letter at a time, as shown in the sample run. Each letter in the word is displayed as asterisk. when the user makes a correct guess, the actual letter is then displayed. When the user finishes a word, display the number of misses and ask the user whether to continue to play with another word. Declare an array to store word as follow:
Store 20 different words in a text file, read them into an array. Randomly pick a number 1..20 and use this word for the current round.
