What do I put after the colons if I have nothing to put there? This is because I only want to check for Primes[k] and nothing more. I usually put some random value in there, but I don't know if this does anything in the code.
I have tried calling a void function using the above method, but when I put a random number in the spot after the colon, I get an error about types not matching or something like that.
Can someone please explain to me what to put after the colon if you have no else statements to execute?
