    Pass by Reference [RESOLVED]

    Hi,

    I found this as a sample Function from an exercise.

    Code:
    int search(const tvector<Student>& list, const string& idnum);
    And I was wondering, is there any difference if the function was declared as
    Code:
    int search(const tvector<Student> &list, const string &idnum);
    What does the ampersand ( & ) means in the 1st code?

    Thanks.
