Where does global static local register variables free memory and C Program instructions get stored?
* These are all implementation defined. Access to `register' specified indentifiers should be as fast as possible, so the compiler may place the value in a machine register. However, the compiler is free to treat a `register' declaration as an `auto' declaration. * Where free memory is maintained is an OS specific concept. Instructions are generally stored in code segement. Local Variables are stored in Stack. Register variables are stored in Register. Global & static variables are stored in data segment. The memory created dynamically are stored in Heap And the C program instructions get stored in code segment.
