Why are you declaring the counter variable on the global scope here? Won't it mess the code if you use multiple loops?

Declaring it like this needs you to start each new loop with

counter=0;

Am I overseeing something?

You are correct that in order to use the exact same variable, you would have to reset it to 0 before each loop; however, he is using the counter variable as an example in the video, and since there are no other loops, it's fine that the counter variable is in the global context.
