this, that, these, and those?! THIS is how much THIS makes sense to me. Please help...again.

Question

this.name=name
Okay, that's confusing enough. But to then do a changeName
and follow it with another
this.name=name
I really don't get it. I thought, since name already equaled this.name, why do you need to declare it again? I mean, it's not like this.name=red and then it changed to blue! This.name=name in both instances! What The Flip-Flop is going on? I know I have asked for help a lot of times but I really REEAALLYY need help. (So much so that I just broke 2 ethics and etiquette laws!)

Answer 1

In this case the second name usually is a variable, so you are assigning to the property object names the name which you are passing by a variable. If you share code maybe you can have more clear that knowledge

Answer 2

Maybe at lesson Overloading operator for C++ you can learn more, like that code

#include <iostream>
using namespace std;

class MyClass {
public:
int var;
MyClass() { }
MyClass(int a)
: var(a) { }

MyClass operator+(MyClass &obj) {
MyClass res;
res.var= this->var+obj.var;
return res;
}
};

int main() {
MyClass obj1(12), obj2(55);
MyClass res = obj1+obj2;

cout << res.var;
}
