Setters and getters in C++

Question

Coming from Java, I am used to doing this:

void setColor(String color) {
    this.color = color;
}

However, I recently switched to C++, and I see a lot of this instead:

void setColor(string c) {
    color = c;
}

Why not this? Is this not recommended?

void setColor(string color) {
    this->color = color;
}

Answer 1

It's the exact same thing. In Java if you had named your parameter c instead of color, you would not have any shadowing and you could easily write

void setColor(String c) {
    color = c;
}

The this in Java (or C++ for that matter) is only needed to specify exactly which color you are referring to: the member variable or the local variable.
