Reaching into the default namespace when using another namespace.

[Jason Heyes]

Can somebody tell me how to change only the main function below so that bar
in the default namespace is assigned 4 and not bar in namespace foo?

int bar;
namespace foo { int bar; }
using namespace foo;

int main()
{
bar = 4;
return 0;
}

Thanks a heap.

I think you want "::bar = 4;"
