This is a C implementation of the game Rock Paper Scissors Lizard Spock, inspired of course by the TV show The Big Bang Theory.
I made this when I was 16 years old and just learning programming. There are many things I'd change about it today, but that would spoil the fun.
gcc rpsls.c -o rpsls
This was originally built using MinGW gcc on Windows. It may or may not work on other compilers/platforms.
