What is the use of unnamed namespaces in OOPS?
The only advantage I know is that they dont need the scope
resolution operator while accessing them. I want to know
some other advantages of unnamed namespaces...

Answer / santosh mundhe
Another advantage is that u can extend namespace within the
same file ....
E.g
#include <iostream>
using namespace std;
namespace
{
int myval;
void funct (int);
}
namespace
{
void funct (int i)
{
cout << i << endl;
}
}
int main()
{
funct(myval);
return 0;
}

Answer / c++ coder
in addition to the advantage mentioned above , there is one
more that the namespace is local to the file and one cannot
use it into another by 'using namespace' since it is
unnamed.
