    1. Make your mind up as to whether this is C or C++.
    Use malloc + free or new + delete.
    Never mix the two.

    In particular, if you do
    char *convert = new char[10];
    Then you MUST do
    delete [ ] convert; // Yes, the [ ] are important.

    Also, 10 characters is woefully inadequate
    > sprintf(convert, "Damage %d-%d", player_mindamage, player_maxdamage);
    The fixed characters account for 8 chars, and then allowing for the \0, leaves only ONE char for BOTH integers.
    Instant buffer overflow.

    You may as well just declare
    char convert[100];
    and save yourself a whole bunch of memory management problems.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
