1:-By default you can't change data members of a constant object..
But it can be made to do so...
can you give me method?

2:-By default all the output in c++ are right justify
can you give me method to have output that are left justify?
Please don't use output like this............

cout<<" Hello"<<endl;

3 :- Say you have created a class named car ...whose data members are
name,owner,model
since model and name of car can't be changed .in any case ...so you will create a constant object of type car so that if you ever tried to change name and model ..compiler gives you an error..
but owner of car can be changed now since you have declared a constant object of type car ..compiler will not allow you
Now My question is ..to give me some method..that i can achieve my both purpose that i can declare a constant object and it will also let me to change name of owner..
I hope now you got my question
2:-------Problem is quite simple...
whenever you execute a Program ..It's output is right justify
say you have to print "My name is hussanal"
By default it will print like this:-

My Name is hussanal

But I want output which should be displayed on opposite side ...........

I think we should create a friend function for that class to change the value of its data members.

This can be done by declaring the data member of const object as mutable.By this Const function can change the mutable data member.Others will remain Constant.

The answer of 2nd question is you have to use some flags
like left,right
```
#include<iostream.h>
#include<conio.h>
void main()
{
cout.setf(ios::left);
cout<<"My name is manish"<<endl;
}
```
for right you can use
cout.setf(ios::right);
