I declared some common value as static.
struct Test
{
.........
static int value;
..............
};
and when I tried to access it as:
Test::value=10;
The error message is as following:
error LNK2001: unresolved external symbol "public: static int Test::value" (?value@Test@@2HA)
hope some experts give me the explanation.
