We cannot use a 'static variable' declared in one file and use it in file 2.Reason: The purpose of 'static' keyword is to retain the value betwwen the function and to restrict thescope of the variable to the file.When a variable is declared as static it will be given memory in global area portion of the process segments with the variable mname prefixed with the file namefor Example: static int k; implies it is stored as "filename.k" in global segment.so if you try to use it in another file the compiler finds the variable prefix and flags out an error.
