Is getchar a buffered function and is it echoed? By echoed I am referring to whether or not values from getchar are printed on the screen twice?
I assume it is about standard output and shell, not so much connected to C itself.

[@sarba85528]

Thank you!! You solved a mystery for me

[@snakeleon]

Thanks for the help!

[@AllTechPage]

Thank you Snake :)
Sorry for the delay..for some unknown reason youtube marked your comment as spam :s so I just saw your comment after reviewing :)

[@c_was8020]

Thanks for this, what an annoying little issue.

[@shail0124]

Thanks!
And we can also use
fflush(stdin);
after taking input to clear buffer

[@Oodelally]

This only works in Microsoft’s C compiler (visual studio) and causes UB in others

[@piyushaneja7168]

So is there any particular rule when we should use getchar() to avoid this problem beforehand Or when we don't get output then we add getchar() snd resolve the issue at that time only
