Which is best LabView or C Programming language ?
They are totally different languages for very different purposes (although there is some overlap, in the area of lab software). C is a low-level general-purpose language which can be used for pretty much any kind of application. It is generally suited to systems/embedded programming and areas where performance or resource usage is critical. LabView is a proprietary graphical environment with its own programming language (Z) and is specifically intended for laboratory type applications. It’s quick and easy to set up simple experimental apps and interface to lab instruments etc, but you wouldn’t want to use it for anything more “general purpose”.
