That's probably because checkprime has unbalanced braces ({}).

I'll describe the algorithm in words. It's your job to write the code. You need a string constant that is 257 characters in length. It's value is a character string containing all of the ASCII...

You're skipping a bunch of characters. For example, if you encounter a "/" and the next character is neither a "/" nor an "*", you do not output it. If you encounter a "/*" and then subsequently...

On line 18. num2 is the upper limit of the loop. It's being modified within the loop. This is bound to either give the wrong result (if you're lucky) or cause an infinite loop, depending on what...
