What is the best programming language to build games. Please tell me. why games like pubg are not written in a single language?

Question

In how much time I would be able to build a good adventurous game as I am a beginner now. I have just started this journey to learn programming language.

Answer 1

See, I would like to tell you, making a game is not a single person work, it can be, provided the game is small(e.g. chess, tic tac toe, etc. )
There is no BEST PROGRAMMING LANGUAGE for games. Each programming language has pros and cons.
For example:
Programs in Python are slow but it's programmer- friendly(providing many modules which help in coding less and in keeping the code well organised)

Programs in C++ are fast but it's a bit hard to code. (Currently all big or small title games are coded in C++. They require MS visual C++)

But as you mentioned that you are a beginner, you should go for C language to understand programming.
If you are familiar with the programming environment then you may learn python for productive game building.

After you gain some confidence you may learn C++ at a COMPETITIVE LEVEL as games are to be highly optimised for the devices it support.

Hope this helps :)
