git clone github password issue

[JustRaspberry]

Greetings,
I am using raspberry pi to do your tutorial from pdf file called 'dht humidity sensor on raspberry pi with gdocs and logging' by ladyada. after typing the following command,
$ git clone
https://github.com/adafruit/Adafruit-Ra ... n-Code.git
I ended up with the following command in terminal,
username for 'https://github.com'
password for 'https://github.com'

What is the username and password for this?
Thank you.

Thank you. It solved the problem. I managed to proceed further untill I got stuck again.
I typed
gcc Adafruit_DHT.c -l bcm2835 -std=gnu99 -o Adafruit_DHT
I received the following error message
gcc: error: Adafruit_DHT.c: No such file or directory

I typed gcc command in directory where adafruit_dht.c file is located.
Also I copy/pasted the file in source directory of bcm2835 and typed gcc command in bcm2835 directory. I received the same error messauge.
Any suggestions are appreciated.
Thank you.

Sorry for the questioning about gcc. I made a typo mistake. It was Adafruit_DHT.C it should be DHT.c a small c
