Hello everyone 
I took a C course as a freshman at the university and I studied a few other languages by myself. I didn’t use my programming skills much in my job, so they’re quite rusty 
and this is one of the reasons I’m taking the course from the beginning. The other reason is that I want to get to know UE peculiarities at a slow, nice pace. That said I definitely know what a loop is but I asked myself what would have I done if I were a kid unaware of loops, just as if I only knew the tools already provided by the course. I ended up writing IsIsogram that way. Obviously, I did this because I enjoy playing around 
and because we’re using just a single HiddenWord which is ‘cake’ and it is conveniently short to play with it. Otherwise, I wouldn’t be showing anything this session because my code was pretty much identical to that of the lessons
