    minizoo.c

    Intended to help us discuss the zoo escape
    assignment structure (and to illustrate sscanf).

    Compile this for easy gdb use:

    gcc -g -Wall -Werror -O1 -fno-pie -no-pie -fno-stack-protector -o minizoo minizoo.c

    Then you can either just run this program (./minizoo)
    or open it with gdb (gdb minizoo).
