This pointer use

#1

Why we are not using this->car_name like this->x and this->y at 5:35 of video?

Hey @nemishgarg1999
Works either ways. You can write this->car_name or car_name, it’s gonna work fine. But it’s important to write this->x = x, x = x won’t work, this is required to differentiate. Similarly for y.

Thanks @mahimahans111

Can you tell me more about why

this->x = x;

is always required as compared to

x = x;

Here when the class member and the variable name which is assigned to the member is same, this keyword has to be used in the constructor to assign value to the class member.
In the statement
this->x = x
The ‘this’ pointer is used to retrieve the object’s x hidden by the local variable ‘x’. The x on the LHS written with this, thus denotes the class member and the x on the RHS denotes the variable whose value is assigned to the class member
