    A quick search of this forum for "how to pick a random number" brings me to How to pick a random number between x and y. Adapt post #6 to your needs.

    Abuse C array indexing rules for fun an profit : char x = "1Q2"[rand() % 3];

    Could easily be expanded to an arbitrary character array using a const char pointer and strlen() instead of hard-coding the array and length.
