An attempt to solve all Project Euler challenges, partly for fun and also as a way of (re)-learning various languages.
These are not necessarily the most efficient, elegant or robust solutions.
For C solutions, C99 is assumed and all solutions have been compiled with at least:
clang -Wall -Wextra -Werrors ${EX_NUM}.c -o ${EX_NUM}
Additional flags may have been used, e.g. if the solution includes the math.h
header or glib.
