Thank you.

Sometimes for certain problems, we might want to think of other easier language for data manipulation. Usually for large input data with space, decimal etc, parsing them using C++ is hard enough. I would switch to Perl gladly. That is if you are open to the idea of using other language to solve your problem.

Is perl easy to learn?

[Silvermaul]

You can write code faster in Perl and it's pretty easy to grasp the basics if you have an idea about programming. Then you just to learn regex and you can do whatever you want with text easily.
