(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;
}
