I am looking for an explanation of what happens in Linux when ctrl+c is pressed to change the current terminal. Could you provide the location of the source file which handles this?

ctrl-c sends a kill signal. This page discusses kill signals (http://en.wikipedia.org/wiki/Signal.h). The code is in the signal.h file (a part of the standard C library).
