Static elements from C

In both C and C++ the keyword static has two basic meanings, which unfortunately often step on each other’s toes:

  1. Allocated once at a fixed address; that is, the object is created in a special static data area rather than on the stack each time a function is called. This is the concept of static storage.
  2. Local to a particular translation unit (and local to a class scope in C++, as you will see later). Here, static controls the visibility of a name, so that name cannot be seen outside the translation unit or class. This also describes the concept of linkage, which determines what names the linker will see.

This section will look at the above meanings of static as they were inherited from C.
