I'm a beginner, so please explain in simple terms. I've tried everything. everything. I know there might be a typo of two of this symbol: "<<" rather than "<" but other than that nothing is happening. I tried "std::" already, but if your telling me I still need to try it, then I will. Though, need something different. Thank you. I've also tried other things. (Please include what I've already tried if you think it is needed)
