What are the most important programming languages that you learned, and which of them is the most important?

Throughout my career I have used around languages. The most important part is not the language. It is being able to visualise the business process in pseudocode first. Many programming languages share the same basic structures, so moving from one language to the next is not complicated for a keen learner.

i advice you with C# so simple language and it's a managed programming language and strongly typed language  rather than C++ and C with meaning that the compiler of the language will never allow to perform any deadly syntax error that could kill your app and all that you have to just writ your code  don't have to free memory space using pointers because garbage collector will do this for you and no need to make any other underground operations the clr and compiler will do that instead  of you 

i  strongly recommend to use visual studio  while programming with c# it have a very nice intellisense and compiler

and best regards

C,,,,,C++,,,,,,JAVA.....................

the most important one C & JAVA

C++

it is a very good language to understand the OOP concepts.

   I prefer (C) language and (VHDL) language 

Turbo Pascal and C languages  is one of important computer languages ,because they are teach you how program and building your capacity in programming logic and all other programming language intersect with them  in  body structure.Also they are  the best  programing language teach you data structure and Object Oriented Programming .pluse you can call assmeblly language in pascal as C as well.

c , c++ ,java python .matlab

and the best is python it is easy language for programming

the most imortant programming launguges is java but i prefer paython

 i prefer python and java languages
