ok, you said that global variables are neither store in stack nor heap......but as we know that memory allocated in stack remains in existence for the duration of a program, and it is sufficient for global variable.....th en why we not use stack for storing of global variables

All the language spec says regards the duration of the storage.
Variables defined inside a function need to live for the duration of the function. Often this storage is referred to as stack storage.
Variables defined outside a function must exist for the duration of the program. Often this storage is called static storage. How this is implemented by a particular compiler is irrelevant.
There is no such thing as a global variable. This is the popular name for variables in static storage with external linkage.
