query regarding Bash

[Roli Srivastava]

Hello sir,

 I am a Linux trainer, and need some help from you.
 If possible, could you please help me with following queries regarding
    bash:

 1.       In which language the GNU shell (bash) has been written? (I
    have read that bourne and korn use the ALGOL and C etc., but I am
    not able to get any information about bash)

 2.       Is it possible to get the code for bash, could you please
    give me the web address etc.
