    Angry Sorting in Alphabetical order

    Guys I need some help to finish this file in sorting. The names need to be sorted in ascending order by the last name.Help

    /* GIVEN A TEXT FILE WITH THE APPROPRIATE CONTENTS, READ THE INFORMATION
    IN THE FOLLOWTING STRUCTURE (FIGURE); THEN, SORT THE NAMES IN ALPHABETICAL
    ORDER ACCORDING TO THE LAST NAME, AND PRINT THE RESULTS IN ANOTHER FILE.
    INPUT FILE: IN_INFO.TXT
    OUTPUT FILE: OUT_INFO.TXT

    Please use code tags. That's making my eyes bleed. Also you probably could have just looked at the thread about four down from this with the same exact topic...

    Hope is the first step on the road to disappointment.
