Answer» hi i m akmal.i m interested in programming.i m beginner and i want to ask how can i run compiler.i failed to do that.thanksWe would like to know more about sure to experience and what your objective is. Do you wish to become a professional programmer? Or are you interested in some of their field where programming would be helpful to you? At the present time systems level programming is done in some version of C or perhaps C++, and there are a number of good versions of these programs. They are written with a common text editor and then submitted to a compiler. If there are no errors but compiler will link the object code into a library and create an executable file. However, perhaps your interest is not in systems level programming. The greatest need in programming at the present time is in applications that are custom made for a specific industry or business. Some of these kind of applications can be written in a script language. A commonly used script language is called Python. This is easy to use and has the potential of being very harmful in specific applications. If you write a very good program application in Python, it also can later become complied okay and has an efficiency that is near that of a system-level program.

False. But compiled VS. interpreted is redundant anyway. a bubble sort in assembly will always be slower then a shell sort in any interpreted language. Besides, most Python interpreters implement Just-In-Time Compilation, like most javascript engines and the .NET CLR. .NET programs are compiled to IDL, which the CLR compiles to instructions specific to the machine being run on as you run it. a good number of script languages do this as well, but convert the actual script language in memory to machine-specific instructions. Still others use a sort of intermediate language that the execution engine can interpret and run faster then the pure script code. You can convert a Python script/application to a actual executable but it is still dependent on a script interpreter- there is no python "compiler" that actually makes the program machine code. this is more an advantage then a disadvantage, since it encourages the creation of cross-platform applications.
