Chapter 12.2, Problem 13STE
Explanation of Solution
Program:
//Header file
#include <iostream>
//For standard input and output
using namespace std;
//Create namespace "sally"
namespace sally
{
//Function declaration for message()
void message( );
}
//Create unnamed namespace
namespace
{
//Function declaration for message()
void message( );
}
//Main function
int main( )
{
{
/* Call the message() function for unnamed namespace */
message( );
/* Call the function message() by "using" directive */
using sally::message;
//Call message() function
message( );
}
/* Call the message() function for unnamed namespace */
message( );
return 0;
}
/* Create function definition of namespace for "message()" function */
namespace sally
{
/* Function definition for message() */
void message( )
{
/* Display message */
cout << "Hello from Sally.\n";
}
}
/* Create function definition of unnamed namespace for "message()" function */
namespace
{
void message( )
{
/* Display message */
cout << "Hello from unnamed.\n";
}
}
Explanation:
The given code is used to display the message from “sally” namespace and unnamed namespace...
