I've installed gcc-9 and g++-9 as written in this answer answer and updated the alternatives as shown in the comment, still when I type man g++ it shows the man page of the previous version. The output of gcc -v and g++ -v is 9.2.1

What version of Ubuntu? – bhordupur Feb 13 '20 at 09:25
ubuntu 18.04 is the version – vib_29 Feb 13 '20 at 09:26
I have ubuntu 16.04 and give me some time I will test it in 18.04 in a docker container – bhordupur Feb 13 '20 at 09:27
What was the old version? – bhordupur Feb 13 '20 at 11:18
Checking for version : $ gcc --version... or $ gcc -v. ... About man pages ( $ man gcc ) : The link made with "update-alternatives" is for /usr/bin/ only, not ///man/ – Knud Larsen Feb 13 '20 at 12:32
@bhordupur, the old version was gcc-7 – vib_29 Feb 13 '20 at 12:40
so what do I do to show the latest manpage, should I create a symlink ? – vib_29 Feb 13 '20 at 12:41
If you want the man page to reflect the selected binary alternative, you should probably add it as a slave when you install the link group – steeldriver Feb 13 '20 at 13:07
is gcc-9 default one?Have you verified that? I could not reproduce it. I guess you better update your questions with more info. – bhordupur Feb 14 '20 at 07:38
@steeldriver I would be grateful if you tell how I could do that – vib_29 May 17 '20 at 13:42
