Everybody knows about the scope, but the real thing is for the storage allocation:-

Memory is devided into four segements namely stack, heap, data, code segments.

Local Variables are stored in Stack.
The memory created dynamically are stored in Heap
Extern, Global & static variables need to retain their values so are stored in data segment.
The C program instructions get stored in code segment 
Register variables are stored in Register.
