/*
Keyword "this"
You can use keyword "this" to refer to this instance inside a class definition.
One of the main usage of keyword this is to resolve ambiguity between the names of
data member and function parameter. For example:
*/
class Circle {
private:
double radius; // Member variable called "radius"
......
public:
void setRadius(double radius) { // Function's argument also called "radius"
this->radius = radius;
// "this.radius" refers to this instance's member variable
// "radius" resolved to the function's argument.
}
......
}
