    Opening files for use by multiple functions

    where do I intialize a file so it can be viewed by more that one function in the same program?

    I tried putting

    FILE *in=fopen("C:\\cs10e\\input5.txt","r");
    above the main, but I get an illegal intiialization error, and if I put it twice, inside the two functions, it doesnt work properly (reading the data).

    You can't do any work aside from simple initialization and declarations in the global namespace, try this instead:
    #include <stdio.h>
    static FILE *in;
    void f ( void )
      /* Blah blah with in */
    int main ( void )
      in = fopen ( "C:\\cs10e\\input5.txt", "r" );
      /* Blah blah with in */
    My best code is written with the delete key.
