in C, if I declare a static variable inside a local strucutre, where does the static variable get placed ? Since the struct is in the stack, will the static variable also be in the stack ?

5Though the Q is tagged c, I feel the pressing need to ask *In what language c or c++?*, `static` structure member has no meaning in c unlike c++. – Alok Save Apr 03 '12 at 07:29

If your intention was C and C++ both then retag it so and add a note saying so. – Alok Save Apr 04 '12 at 06:57

In current C the keyword static is meaningless inside a structure. You should get an error from the compiler.
If by "static" you mean "not allocated using malloc": the member of a structure is always stored in the same place as the rest of the structure. If said member is a pointer, it can point to memory in the same region or not.

"static" haiku: Wonderful `static`; Keyword, object lifetime, scope; Much more than `auto`. – Michael Burr Apr 03 '12 at 07:58

In C++ static variables will be initialized when you first time use their class. In C they are not allowed since C compiler needs to store the whole struct in the same type of memory. About their storage see Where are static variables stored (in C/C++)?
