MARKET: Useful for both beginning and intermediate C++ programmers. . | Programming Projects 497 10. The program would behave exactly the same. However most authorities favor using the using declaration as we have done in Display . Note that with either there are still two different functions named readHour. The one in Display is different from the one defined in the unnamed namespace in Display . 11. Hello from unnamed. Hello from Sally. Hello from unnamed. 12. Outer. Inner. Inner. Programming Projects 1. 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 place a declaration of void f in namespace A. In file place a declaration of void g in namespace A. In files and 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 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 provide 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 the above write a one page description of how to create and use namespaces and separate compilation in your environment. 498 Separate Compilation and .
