I always see solutions to some questions regarding classes, and they have (*this) , I don't understand when to use it and how to use it. Does it just mean that we're referring to something? Please...

O ok, that makes sense. Thank you for your help, really appreciate it.

ok so basically it means that
*b=&a
b=10
?

int a = 10;
int* b = &a;
int c = 4;
int* d = &c;
(*d)++;
d = b;
*d = c - *b;
cout << a << " " << c;

Output
