The paragraph is a bit nonsensical, where it suggests using a singleton factory as a workaround to using a singleton.
Yes, the solution is to make a single instance and pass it around. You can use the private and friend features of C++ to prevent people from creating second copies.
Don't get an A+ certification unless you're going to use it somehow between the time you get it and the time you get your bachelors in computer science.
It is supposedly trivially easy to get, so don't spend any money on a course.
you normally would use this singleton method for a configuration accessor class
Hah! If only you knew the Hell I went through thanks to people thinking that.
or a group of data that needs to be shared throught the app without passing a class object around
This situation (the operative word being "needs") never exists.
If you ask me, the best use of singletons is to protect yourself from "junior" programmers who are liable to want to open up a fresh db connection in some inner function.
Let's learn some ways to write code more efficiently. If your code is hastily edited and cut for the sake of an example or you can't use things you've never learned and such, you don't need to reply back explaining yourself. ...
const string file = "File.TXT";
// don't declare variables and assign them with values,
// only to overwrite those values later. How can you
// stand it?
string first = cBoxFirst.Text;
string last = cBoxSecond.Text;
// your stream reading code looked good, but note
// you have this function available:
string[] array = File.ReadAllLines(file);
// note that you could have used
// string[] array = nList.ToArray();
// in your previous code.
// you probably would want to sort your array here...
int fIndex = Array.BinarySearch(array, first);
int lIndex = Array.BinarySearch(array, last);
If you're a horrible programmer looking for a horrible programming job, then a certification might impress somebody, somewhere. But any reasonable employer will not count them in your favor. They will only be counted against you. You should have things that actually boost your resume like projects you've worked on for fun, that show how smart you are. A resume that says "I actually did stuff" means a lot more than one that says "I passed some exam and present this as evidence."

I think that's it. There are some practical programming books too... do you want a list of those?
ArrayList is in the System.Collections namespace and List<> is in the System.Collections.Generic namespace. Use List<double> instead of an ArrayList, and use System.Collections.Generic instead of System.Collections. There's no reason to use obsolete collection types here.
Not much, the usual intelligence level it seems, maybe you should join multiple forums; maybe a socket question will come up in one of them. Do some RSSing and scraping and you can have a nice socket-related feed.
If you could get a certifiably awesome certification, that would be nice. If you're getting a degree, why do you need a certification? I do not understand the IT world.
Yeah! What if they just post stupid crap that they think makes them sound sorta intellectual? Or posting pedantic crap that worries about 'pure conjecture' - get a life.
Wow, being a bully. How's that working out for you?
Wouldn't this advice depend on your location? Reveal that information to us. I'm guessing by your hair color and sun-exposure level that you're Canadian or Alaskan.
Edit: on the other hand, the lipstick makes me think you must be some kind of english dandy.
You people are so sexually repressed. There's nothing so cathartic as seeing a well-animated tentacle monster trapping a 12-year-old virgin in a library and challenging her to a Boggle contest, where the winner gets tickets to the next Jonas Brothers concert.
No one should be here to throw dirt on anyone elses beliefs, regardless of what they are.
But what if they're stupid? Why shouldn't we throw dirt at stupid beliefs? Like the belief that one should just make pronouncements and feel proud at the fact.
It's pure conjecture.
No, there is past exposure to information influencing people's opinions. Nothing is pure conjecture.
So the question is: How to detect when last character found? You surely know how to do that? Well then, finding the recursive function that outputs them in reverse order is a simple matter of mentally stimulating exploration! Good luck!
I would post my "marks", but they are all links to movies involving large groups of black men fornicating with one white female midget, and serious geeks like you wouldn't be interested.
