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;
}

Given this particular defined class;
class strtype {
char *p;
int len;
public:
char *getstring() { return p;}
int getlength() { return len;}
add two constructor functions. Have the first one take no parameters. Have this one allocate 255 bytes of memory (using new), initialize that memory as a null string, and give len a value of 255. Have the other constructor take two parameters. The first is the string to use for initialization and the other is the number of bytes to allocate. Have this version allocate the specified amount of memory and copy the string to that memory. Perform all necessary boundary checks and demonstrate that your constructors work by including a short program.

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; }
// ...
};
