Uhm. i dont personally have experience in 5 languages yet. but from what i have heard... C++, python, ruby, perl, and batch are up their. but this is mostly what i have heard.
I think you've acquired some false information ... without taking platform in to consideration, I'd say the 5 most commonly used programming languages are:
1. C/C++ 2. Python (little experience but it's a good language 3. PHP 4. Java (don't really like this language somehow but it's a good language) 5. Shell (Unix style :D :D)
I believe the 5 languages most commonly used for new development are: Java, C, C++, PHP, and C# -- in that order. Objective-C is gaining very quickly though, especially thanks to the iPhone and iPad.
If you were to ask about my 5 favorite languages, they are: Python C++ Objective-C Javascript PHP
I don't know if you Googled or not (your comment about most popular languages totally match with this website, which is the #1 Google result ;)) ) but it doesn't matter. All I wanna say is that I think this discussion is about your top 5. I think so because 'most popular languages' topic isn't really a discussion - it's pure statistics.
