I'm learning c++. Which language should i go for after completing c++?

Answer 1

do what you want there is no specific language to go after

Answer 2

Dont try to be in hurry to learn many languages. ..completing a course here doesn't mean you know it well now.
code ...practice. ..solve problems...do competitive programming.
once you get feelings that yes now you know this language and have no problem with syntax and can code anything if you get logic then move on to learn others.
and to choose next languages. ..think what things you couldn't do with this language, what things you want which is not available in this language but available in other.
I am making complicated now :p
