Well, I love C, as I that's the programming language that I learned first, and my logic was developed using C only, but then I don't know C that much, just about medium level which I learned in college and got polished when I learned Data Structure, and more polished when I used it under Linux.
My most preferred language is PHP, don't know why, but I find it really easier to grasp, and there are many PHP Developers out there and lots of forums. It got more polished when I started doing Freelancing on web development on my free time and worked on few projects.
Then I learned Python, which I liked most.
But still PHP is my most preferred language
And if you want to know most hated language within the list, I'd vote for Java
(Sorry, Java Lovers)
