You chained the strcmp checks wrongly there I think. Try: while(!(strcmp(...) == 0 || strcmp(...) == 0 || ...)) { }

`!=` 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! }

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

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