You need to return a reference
, otherwise you are doing a copy of the object
.
Try to add the method:
Code: CPP
Test::Test(Test& test) {
cout<<"Test::Test(Test& test)\n";
}
Better shall be:
Code: CPP
#include <iostream>
using namespace std;Correct should be:
class Test
{
public:
Test() {};
Test(Test& test);
Test& Display(); // Function 1
Test& Show(); // Function 2
Test& Result(); // Function 3
};
Test::Test(Test& test) {
cout<<"Test::Test(Test& test)\n";
}
Test& Test::Display()
{
cout<<"Function 1"<<endl;
return *this; // Return this pointer
}
Test& Test::Show()
{
cout<<"Function 2"<<endl;
return *this;
}
Test& Test::Result()
{
cout<<"Result 3"<<endl;
return *this;
}
int main()
{
Test Obj;
//Here i have called all the three function in a sequence.
Obj.Display().Show().Result(); //This is called Function Chaining
}
