Answer 1

You chained the strcmp checks wrongly there I think. Try:

while(!(strcmp(...) == 0 || strcmp(...) == 0 || ...)) {

}

Answer 2

`!=` is not the correct way to compare strings in c, that's why your code doesn't work. Have a look at the `strcmp` function!

if(strcmp(monster, "Large") == 0) {
//the strings are equal!
}

Answer 3

Your way to loop until true is correct just use the strcmp method instead of != to compare it inside the while loop

Answer 4

No, if the user inputs the correct value you expect then the loop will not execute.
