You should give a better description of your requirements (for your post on CodeReview). If you literally just want efficiency and the ability to enter multiple names, then int main() { string s1; while ( true ) { cout<<"Enter Student Name: "; getline (cin, s1); } } would satisfy those requirements. I'm not saying that someone would seriously suggest this, but that you should put enough time into your question so that this no longer fits your question.JaMiT 46 secs ago

Hi and welcome to SO. SO is not a forum, tutorial/guide nor a personal help desk. Even if it might sounds harsh to you, your topic does not belong here nor does it have any value for SO. SO is for programmers that already know how to prgram and stuck with very specifc coding issues. Issues that they cant resolve on their own even after own research efford. For code review, use the stackexchange codereview: codereview.stackexchange.com - As your topic missing a spicific coding issue and do not meet the SO guidelines, it will be flagged for closure. — tacoshy 19 secs ago
Stack Overflow's main focus is around specific, answerable questions about a given topic or code problem. Questions seeking a code review are off-topic for Stack Overflow, as they can often lead to opinionated answers. You might be able to find an answer on Code Review, but please keep in mind what topics you can post about there and how to ask a good question. — Hoppeduppeanut 5 secs ago

It sounds like you're really asking for a code review? If so, there's a specific StackExchange Code Review site where your question might fit better - check their guidance of course before you post though. Here at StackOverflow we tend to deal with "this isn't working" type problems more than "could I do this a different way"? — ADyson 31 secs ago

@Pat.ANDRIA et. al when suggesting users post on CR it would be great if there was also a suggestion like "Please read the relevant help center pages like 'What topics can I ask about here?' and 'How do I ask a good question?". If the post was posted on CR in the current form, part of the description (i.e. "I also need to calculate the length of the path through the points.") might likely lead to the post getting closed as off-topic since it isn't working properly yet. — Sᴀᴍ Onᴇᴌᴀ 31 secs ago
