(Solved)
The copy constructor is also involked when a function generates the temporary object that is used as the function's return value. With this in mind, consider the following output:
constructing nomally
constructing normally
constructing copy
This output was created by the following program. Explain why, and describe precisely what is occuring.
#include
using namespace std;
class myclass {
public:
myclass();
myclass(const myclass &o);
myclas f();
};
// Normal constructor
myclass::myclass()
{
cout << "Constructing normally\n";
}
// Copy constructor
myclass::myclass(const myclass &ocout << "Constructing copy\n";
}
// Return an object.
myclass myclass::f()
{
myclass temp;
return temp;
}
int main()
{
myclass obj;
obj = obj.return 0;
}

(Solved)
Imagine a situation in which two classes, called pr1 and pr2, shown below, share one printer.Further imagine that other parts of your program need to when the printer is in use by an object of either of these two classes. Create a function in C++ called inuse() that returns true when the printer is being used by either and false otherwise. Make this function a friend of both pr1 and pr2.
class pri1 {
int printing; //...
public:
pr1 () {printing = 0}
void set_print (int status) {printing = status;}
// ...
};
class pr2 {
int printing;
// ...
public:
pr2 () {printing = 0;}
void set_prt status) {printing = status; }
// ...
};

(Solved)
When an object of a derived class is assigned to another object of the same derived class, is the data associated with the base class copied? To find out, use the following two classes and write a program that demonstrates what happens.
class base {
int a;
public:
void load_a(int n) { a= n; }
int ge() { return a;}
};
class derived : public base {
int b;
public:
void load_b(int n) {b=n;}
int get_b() {return b;}
};

(Solved)
Using the stack class, write a function called loadstack() that returns a stack that is already loaded with letters of the alphabet (a-z.). Assign this stack to another object in the calling routine and prove that it contains the alphabet. Be sure to change the stack size so it is large enough to hold the alphabet.
