Is there an option to know 5 programming languages?

Question

C++ / C#

From
C++
Java
Python
R
You need to somehow know all these languages ​​perfectly well. What do you advise, comrades?

Answer 1

In my opinion, it’s normal to know several languages ​​​​(don’t forget about technologies, libraries, frameworks, etc. around them, it’s usually not long to learn the language itself, but it’s of little use), it’s another matter that the “basic” ones you use most often, most likely there will be 1-2, and the level of knowledge (as well as their relevance) and experience in others will be lower.

Answer 2

Everything is possible, but you will not know any of them well.
If python + R is still clear, then in the case of c, pluses and java, it is completely incomprehensible, why?

Answer 3

Um...learn, practice, don't you? Although the goal of "knowing 5 programming languages" is completely incomprehensible to me, but it is quite possible.

Answer 4

What do you advise, comrades?

But seriously - you can, but why?

Answer 5

Perhaps knowing one of ... move on to the other. For example, it is much easier to leave the pros in Java . Or find something in common between R and Python . Regarding your question, why ? As said above - "you will not know any of them at an acceptable level"

Answer 6

You have to learn C++ all your life and you won’t know it to the end, you will discover new things every time.
Do you need it now? for the basics and what is being imposed at the university.
Java and Python have J-python can apply knowledge. Also C-python.
As stated above, most of the time you will be using at most 2 languages.
Try with Python and embrace J or C whichever you prefer. If it seems a little, go to the clean ones.
What do you mean by "excellent"? Labs at the university are then real, the question is in the knowledge base at the moment.
