People use C++. The STL is very convenient as you get most datatypes from it with less syntactical overhead than in Java (esp. in C++ 11). In particular thanks

People use C++. The STL is very convenient as you get most datatypes from it with less syntactical overhead than in Java (esp. in C++ 11). In particular thanks to operator redefinitions and "auto" type inference. Python is more concise but it can be too slow for certain tasks, and the lack of static typing can be counterproductive.
