You can check the .map file.

If globals and local statics are explicitly initialized,
they are in the data segment, otherwise they belong to bss.

Btw. avoid

    static int bar = 0;

as this will put two bytes in the data segment and waste
a two byte copy in flash memory for initialization.

    static int bar;

will put the variable in bss, which is automatically cleared
during initialization.
