Answer:

Let us see a namespace “Test”,

namespace Test
{
    class TestObject
    {
    public:
        void DoSomething() {}
    };
    void Func(TestObject) {}
}

Now let see three ways to access the members of the namespace “Test”.

Test::TestObject test;
test.DoSomething();
Test::Func(test);

using Test::TestObject;
TestObject test;
test.DoSomething();

using namespace Test;
TestObject test;
test.DoSomething();
Func(test);
