I feel like I like my stuff too spaced out… 
You can try putting WORD_LENGTH on the same line as "Can you guess the " so it’ll look like
cout << "Can you guess the " << WORD_LENGTH;
Also the multiple endl can also be put on the same line, for example:
cout << "You said " << Guess; << endl << endl;
Although I’m not sure if this is good practice as I’m actually on this exact lesson and came to post my screenshot
