It works good if you get the word right, but when it starts if i get all my guesses wrong and then type y to restart it does not, it just stays put..

common mistake when you use global variables.

.................
const int MAX_WRONG = 8; // maximum number of incorrect guesses allowed before death, change your total lives here
    wrong=0;//add this.
    random_shuffle(words.begin(), words.end());
.................
