• Finding C#-style unescaped strings using regular expressions

  - by possan

  I'm trying to write a regular expression that finds C#-style unescaped strings, such as string x = @"hello world"; The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example string x = @"before quote ""junk"" after quote"; This should be an easy one, right?

• How can make a variable (not class member) "read only" in C#

  - by devfreak

  Hi, I'm new to the C# world and I can't find a method to declare read only variable in C# (something like declaring "const" variable in c++). Is there one? I'll give you an example: ... int f() { return x; } // x is not const member ... void g() { int readOnlyVar = f(); // is there a method to declare readOnlyVar as read only or const // Some code in which I want to restrict access to readOnlyVar to read only }

• C/C++ Struct vs Class

  - by m00st

  After finishing my C++ class it seemed to me the structs/classes are virtually identical except with a few minor differences. I've never programmed in C before; but I do know that it has structs. In C is it possible to inherit other structs and set a modifier of public/private? If you can do this in regular C why in the world do we need C++? What makes classes different from a struct?

• As a CS major, should I take more EE courses?

  - by fakeit

  I have taken enough cs courses to know that I'm not interested in hardware. I'm much more interested in programing for the web. Now, I'm nearing the end of my degree, and I'm presented with the option to take some higher level EE courses than the intro I took freshman year. Are there any real-world-job-boosting reasons I should take more EE course? Any courses in particular that people think would be helpful?

• In Java, is there a way to write a string literal without having to escape quotes?

  - by Matthew

  Say you have a String literal with a lot of quotation marks inside it. You could escape them all, but it's a pain, and difficult to read. In some languages, you can just do this: foo = '"Hello, World"'; In Java, however, '' is used for chars, so you can't use it for Strings this way. Some languages have syntax to work around this. For example, in python, you can do this: """A pretty "convenient" string""" Does Java have anything similar?

  - by cannyboy

  Is there a library or good tutorial which covers creating in-app settings, like this: http://img.skitch.com/20090625-s8bf6ahybwe3cesd1id38h3nt.jpg What I would like is if it: doesn't use the built-in Settings app is controlled by a plist file with various Dictionaries and Arrays creates a nice looking table view allows text fields as well as switches and sliders and ticks etc doesn't have any of the annoying problems I've come across when trying to build my own version (not scrolling to show the textfield, cells disappearing) It would appear that the iphone dev world is crying out for such a thing.

• What type of programs are C/C++ used for now?

  - by Ryan Detzel

  I started off with C in school, went to Java and now I primarily use the P's(Php, Perl, Python) so my exposure to the lower level languages have all but disappeared. I would like to get back into it but I can never justify using C over Perl or Python. What real-world apps are being built with these languages? Any suggestions if I want to dive back in, what can I do with C/C++ that I can't easily do with Perl/Python?
