OOPs Concepts in C++ || Part-1Coding Ninjas is the largest coding education platform where

Courses are really well structured If you will work hard , then
you will definitely get results The course makers have
already cracked big tech companies. If I talk about this
object , there is only an integer , it is of 4 bytes. When I
create this type of objects , it will take the size of its
properties. A class is actually a type of templet there should
be a health named integer When I write hero h1 , I made an
implementation of this. here place some value in health.
There is health , here we put value in it. A block got reserved
in memory , where data of this health got filled In short,
there was an integer when I made its object.
These are my some properties , I put them here There will be
health , level , health , now if I want to print them then how
will I do it Comment it Here we have already created h1 , if
you want to access it Lets name it Ramesh. If I write public
here then both will give error because both became private.
By default your access modifier in class is private. Public
means we can access it inside and outside the class. Private
means you can access them inside the class only. Public is
public, private is public and private is private. Bhaiya is a
child class concept. We have a concept of getter /setter , we
will use it. If any data member is private in your class, you
can access it using getter and setter. If anything is marked
private then I can use getter to read it. If you want to check
only user A can change it and no other can do it. There also
setter can be used to fetching/read setter is for putting any
condition.
You have to study about padding, greedy alignment and
greedy alignment. These are the things you will not find in
paid courses also. If you read it once then this will become
clear to you. I have not seen this in any online test till now
