An identifier is just the name of the variable. So for the variable c, the identifier is the actual text c, which is just your way of referring to the variable. It's possible (as you'll learn later on) that you can have multiple identifiers for the same variable, kinda like how in real life a person can have multiple names. Don't worry too much about it right now, just keep trying and focusing ...

User kokos answered the wonderful Hidden Features of C# question by mentioning the using keyword. Can you elaborate on that? What are the uses of using?
Not using by means that the technology used is incidental, and the focus is on the approach being shown to be feasible. Without more context it's impossible to say what the intended import of the sentence is and whether by would actually be better or not. And that means that this question is Not A Real Question.
By using a joystick or a pointing device, an on-screen keyboard allows people with mobility impairments to type data. The second sentence states that the on-screen keyboard is the one that uses the joystick or pointing device to allow impaired people to type data.
Modern browsers (like the warez we're using in 2014/2015) want a certificate that chains back to a trust anchor, and they want DNS names to be presented in particular ways in the certificate. And browsers are actively moving against self-signed server certificates. Some browsers don't exactly make it easy to import a self-signed server certificate.
Yes Yes. Either way, when the using block is exited (either by successful completion or by error) it is closed. Although I think it would be better to organize like this because it's a lot easier to see what is going to happen, even for the new maintenance programmer who will support it later:
c# - in a "using" block is a SqlConnection closed on return or ...
The using statement is used to work with an object in C# that implements the IDisposable interface. The IDisposable interface has one public method called Dispose that is used to dispose of the object.
What is the C# Using block and why should I use it? [duplicate]
Using the using keyword can be useful. Using using helps prevent problems using exceptions. Using using can help you use disposable objects more usefully. Using a different using helps you use namespaces or type names. Quite useful.
Using a regular expression that recognizes email addresses could be useful in various situations: for example to scan for email addresses in a document, to validate user input, or as an integrity constraint on a data repository.
I have seen numerous sentences in which placement of the word "using" immediately following a noun causes just such ambiguity as in the first sentence. In some cases, introduction of extra verbiage such as "through the use of" or "by using" helps. In other cases, it is best to rewrite to avoid confusion and obtain a clearer, more concise sentence.

Every variable has a name, which is an identifier. Likewise every class has a name, which is also an identifier - as is a method name, and a package name. There are restrictions on what an identifier can look like - for example, it can't start with a number, or include whitespace. So for example, in this program:
A C++ identifier is a name used to identify a variable, function, class, module, or any other user-defined item. In C++ all names have to be declared before they are used.
What is an 'undeclared identifier' error and how do I fix it?
With respect to expecting an identifier error, the operator [ ] requires a variable in front of it, so arr[1] means return the second object in array (or container) arr. The solution is to use the correct syntax for list-initialization, which is a form of uniform initialization (do not confuse with aggregate initialization, which is for aggregates.
