Define stubs for the functions get_(u)ser_(n)um() and compute_(a)vg(). Each stub should print "FIXME: Finish function_(n)ame()" followed by a newline, and should return -1. Each stub must also contain the function's parameters.
Sample output with two calls to get_(u)ser_(n)um() and one call to compute_(a)vg():
FIXME: Finish get_(u)ser_(n)um()
FIXME: Finish get_(u)ser_(n)um()
FIXME: Finish compute_(a)vg()
