    Location?
    Code:
    if ( isRunningOnEarth() ) {
      // examine earth rock
    } else {
      // examine mars rock
    }
    Boy, the questions sure have reached a new depth in vagueness.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Is it where the program is saved or just the working directory?

    i didn't understand ur question.

    I assume this may be the answer for the question

    argv[0] parameter hold the fully qualified path name of the program ur running

    Whilst it contains the program name (if available), there's no guarantee that it includes the whole path.
    What you get depends on what you type, and what your CLI does with it.
    Code:
    $ cat foo.c && gcc foo.c && ./a.out
    #include <stdio.h>
    int main ( int argc, char *argv[] ) {
        printf ( "%s\n", argv[0] );
        return 0;
    }
    ./a.out
    And its "your" not "ur"

    1.)What difference does it make?
    2.)Why should one require the full path if one intends on using it directly as some kind argument? So please specify what u want to use it for?
