Please redo the C++ programming exercise #16 below so that all of the named constants are defined in a namespace.

#16. What is the output of the following C++ code? (2,5,6)

int x = 15;

int y = 3;

if (x + y > 17 | | y - x < 20)

{

y = x - y;

x = y + x;

cout << x << " " << y << " " << x - y << " " << x + y << end1;

}

else

{

x = y - x + %5;

cout << x << " " << y << " " << x - y << " " << x + y << end1;

}
