c++ - Changing the linkage of a name -


an attempt change linkage of name i made in code. legal in c/c++?

static int = 2; int i;  int main() {    return 0; }

in c++ code ill-formed (you have multiple definitions of variable i) i.e standard conformant compiler required issue error message

$3.2.1 (c++03)

no translation unit shall contain more 1 definition of variable, function, class type, enumeration type or template.

in c99 code invokes undefined behaviour because 6.2.2/7 says

if, within translation unit, same identifier appears both internal , external linkage, behavior undefined.
