Here Is Some Code

Short Answer

Here is some code.There are only two outputs,one a message from the unnamed namespace the other a message from the Savitch namespace.Tell which line generates which message.
#include <iostream>
using namespace std;
namespace
{
void message();
}
namespace Savitch
{
void message();
}
int main()
{
{
message();//a)
Savitch::message();//b)
using Savitch::message;
message();//c)
}
message();//d)
return 0;
}
namespace Savitch
{
void message()
{
cout << "Message from NS Savitch\n";
}
}
namespace
{
void message()
{
cout <<"Message from unnamed NS\n";
}
}
1)List the letters of the lines that give the message from the unnamed namespace: ____________________
2)List the letters of the lines that give the message from the Savitch namespace: ____________________
