say, if you had parallel arrays containing the sales person id, the month, and
the sales figures (for that person in that month), sorting on sales figure and
preserve the order of figures within the data about the same person:
 
    Original Data:
           id month sales
        +-----+ +-----+ +-----+
        | 432 | | 8 | | 89 |
        +-----+ +-----+ +-----+
        | 123 | | 8 | | 116 |
        +-----+ +-----+ +-----+
        | 555 | | 8 | | 203 |
        +-----+ +-----+ +-----+
        | 432 | | 9 | | 105 |
        +-----+ +-----+ +-----+
        | 123 | | 9 | | 143 |
        +-----+ +-----+ +-----+
        | 555 | | 9 | | 187 |
        +-----+ +-----+ +-----+
 
    Sorted by sales:
           id month sales
        +-----+ +-----+ +-----+
        | 432 | | 8 | | 89 |
        +-----+ +-----+ +-----+
        | 432 | | 9 | | 105 |
        +-----+ +-----+ +-----+
        | 123 | | 8 | | 116 |
        +-----+ +-----+ +-----+
        | 123 | | 9 | | 143 |
        +-----+ +-----+ +-----+
        | 555 | | 9 | | 187 |
        +-----+ +-----+ +-----+
        | 555 | | 8 | | 203 |
        +-----+ +-----+ +-----+
 
is that possible to do this in c++? Thanks!
