This keyword use?

what was this keyword used for in this video of car sorting probllem

Hello @mahfoozhaque91
Basically we can use this keyword to refer to data members of our object
And incase constructor have same argument names as that of data members then this can be used to point to data member

So here assum

class ABC{
int x;
ABC(int x){
    this->x=x;  //here this->x points to class x
                      //and RHS x is local argument u are receiving

}
}
