Code is not getting burn in Arduino Uno

Hi,
While burning the code in Arduino board the code does not get burn rather i get this thing...
Avrdude: skt500_getsync(): not in sync: resp=0x00
help me if someone faced this problem earlier...Thanks

Its been a common question, search the forum for the string "Avrdude: skt500_getsync(): not in sync" and you'll probably find a few things.

To start off with, do you have anything plugged into pins 0 and 1, if so disconnect those or use different pins. If you need a second serial interface, you can search for examples using the SoftwareSerial over different pins.

The issue is resolved. What i did to resolve the issue was checking weather the arduino board and the communication port is correctly selected or not then i re-extracted the arduino-1.5.6-r2 and the sketch got uploaded
