I've found that even with trivial programs which only have one source
file, putting all the function definitions before main can be a pain,
because if one function needs to call another you have to make sure
the function being called has been declared before you define the
function which can call it. If there are lots of ways in which
functions can call each other you might find that there is no way you
can order the definitions without getting compile time erros, so
prototyping becomes unavoidable. That might just be a case of bad
design though, and in any case I've moved onto using multiple source
files and header files.
