Q: i am dr. bamaselvakumar bought i phone 5c on november 2013 now had an problem in that. the problem is while i connecting the charger it is not charged .

Did you get it checked by an Authorized Apple Service Provider?

Did you try another USB cable or adapter?

Since that is likely to be hardware related, you should get it serviced by the Authorized Apple Service Provider.

If they can't find a solution to fix that, Apple offers to replace the whole unit for a service fee, check this page for the exact amount for your country:

Out-of-warranty repair service
If your repair isn’t covered by Apple’s One Year Limited Warranty, AppleCare+, or AppleCare Protection Plan, your iPhone might be eligible for out-of-warranty service. For example, liquid damage isn’t covered by warranty but might be eligible for out-of-warranty service. Some damage isn’t eligible at all, for example if your device has been broken into multiple pieces. See Apple’s Repair Terms and Conditions for complete details.

Have you tried cleaning the charging port with a wooden toothpick? You'd be surprised at the amount of fluff/gunk that gets built up in there, preventing a good connection between the charger and the pins.
