C# PROGRAMMING –MAIN DESIGN GOALS
C# is a popular programming language these days, and it was designed from inception to provide a simple, clean, general purpose programming language for those intending to work within the confines of Microsoft’s .NET framework. Since then, it has been approved as one of the standard languages by both ECMA and ISO, making C# programming an essential tool in every programmers’ kit.
Different languages have different uses and specialties, and C# was designed for programmers to be able to use it to create different components for use in software that would be deployed and distributed en masse, to live use environments. This means that designers had to really put an emphasis on making the actual source code extremely compatible and portable. Those already familiar with C or C++ should definitely notice this emphasis.
Another particular point of emphasis during design was focus on internationalization of the language; it was intended from inception to be available all over the world, and to see all sorts of different implementations based on variance in regional programming technique. The resultant use should help the language develop sophistication as it is refined throughout different versions.
Unlike Java, Python does not have a string contains method. Instead, use the in operator or the find method. The in operator finds treats the string as a word list whereas the find method looks for substrings. In the example shown below, 'is' is a substring of this but not a word by itself. Therefore, find recoginizes 'is' in this while the in operator does not.
s = "This be a string"
if s.find("is") == -1:
print "No 'is' here!"
else:
print "Found 'is' in the string."
if "is" in s:
print "No 'is' here!"
else:
print "Found 'is' in the string."
#prints out the following:
Found 'is' in the string
No 'is' here!

Many of us who have iPhones download every interesting app we find on the App Store, especially when they’re free. They can range from a simple payment method app, to a game, to a measurement tool. But, as you may have noticed, our phones become cluttered with tons of pages that we have to swipe through to get to an app that we need on demand. However, with an update by Apple that came out not so long ago, you are able to group your applications into categories that are easily accessible, for all of you organization lovers.
To achieve this grouping method, take a hold of one of the applications you want to categorize. Take a game for example. What you want to do is press your finger on that particular application, and hold it there until all of the applications on the screen begin to jiggle. This is where the magic happens. Drag it over to another game application you want to have in the same category, and release. Your applications should now be held in a little container on your screen. However, a step ago, if you did not have another game application on the same screen, and since you can’t swipe, try putting the held game application on any application you choose, and simply remove that extra application from the list, after moving over another gaming application from a different page.
