The Tradition of Sharing

Help your friends and juniors by posting answers to the questions that you know. Also post questions that are not available.

To start with, Sr2Jr’s first step is to reduce the expenses related to education. To achieve this goal Sr2Jr organized the textbook’s question and answers. Sr2Jr is community based and need your support to fill the question and answers. The question and answers posted will be available free of cost to all.

Separate Compilation And Namespaces

Question:1 | ISBN:9780132846813 | Edition: 5


This exercise is intended to illustrate namespaces and separate compilation in your development environment. You should use the development environment you regularly use in this course for this exercise. In a file f.h, place adeclaration of void f( ) in namespace A . In a file g.h , place a declaration of void g( ) in namespace A . In files f.cpp and g.cpp , place the definitions of void f( ) and void g( ) , respectively. Place the definitions of void f( ) and void g( ) in namespace A . The functions can do anything you want, but to keep track of execution include something like

cout << "Function_Name called" << endl;

where Function_Name is the name of the particular function. In another file, main. cpp , put your main function, #include the minimum collection of files to provide access to the names from namespace A . In your main function call the functions f then g . Compile, link, and execute using your development environment. To pro- vide access to names in namespaces, you may use local using declarations such as

using std::cout;

or use local using directives such as

using namespace std;

inside a block, or qualify names using the names of namespaces, such as std::cout.

You may not use global namespace directives such as the following which are not in a block and apply to the entire file:

using namespace std;

Of course you must handle namespace A and function names f and g, in addition to possibly std and cout.

After doing this, write a one page description of how to create and use namespaces and separate compilation in your environment.
