code written (I know it's bad, sorry, I'm a new C++ student) but
cannot figure out how to make my number display 75.0 instead
of 75. I'll attach a screenshot of what it shows currently. It
shows the numbers 75 and 50. I need it to show 75.0 and 50.0
instead. I will provide my current code below too.
