What are the advantages of the 'this' keyword in C++?

Question

One that I've found is that it helps prevent unessesary global object instantiations which would otherwise compromise security bridges:
Consider something like this;

Myclass obj;
class Myclass
{
public:
Myclass (int a,int b,int c): day (a),
month(b),year(c){}
void date()
{
cout << day << " " << month << " " << year<<endl;
}
printInfo()
{
obj.date();
}
private:
int day, month, year;
}

You don't normally need to use this. There are two situations that require it. If you declare a parameter, local variable, or local nested function with the same name as a property or method, that definition hides the class name so this.name lets you access it. If you need to access the entire object to pass as an argument, this is the only way to do so.
