c++ - Can these two functions be combined into one? -

i've finished working on mini task that's described in comment block in code below, i've been trying make code better combining getraredigits , displayraredigits 1 function. no matter do, logic ends breaking. can explain me if it's possible these 2 functions combined? ^_^

your 2 functions big , clunky is. that's difficult avoid, combining them 1 not idea.

instead try figure out logic common them , put individual functions can use get… , display… functions.

also should have @ continue , break break out of loops. despite popular belief goto viable option break out of multiple loop levels , can used simplify code , make shorter , easier comprehend.
