Define stubs for the functions get_user_num() and compute_avg(). Each stub should print "FIXME: Finish function_name()" followed by a newline, and should return -1. Each stub must also contain the function's parameters.
def get_user_num():
print("FIXME: Finish get_user_num()")
return -1
def compute_avg(num1, num2):
print("FIXME: Finish compute_avg()")
return -1
