    just set each variable to some value when the loop starts
    Code:
    int num;
    int i;
    for(i = 0; i < 5; i++)
    {
       num = 0;
       // blabla
    }
    Use rewind(FILE*) to reset a file pointer back to the beginning of the file.

    Code:
    int num, i;
    
    for( num = i = 0; i < 5; i++, num = 0 )
    {
    
    }
    Remember, you can use all portions of the loop to set/test/whatever more than one value or function.

    Hope is the first step on the road to disappointment.
