When I am using copy constructor it not making shallow copy

#1

my class car has 2 object B and C.
C is copy of B (C is made using copy constructor). Now when i am changing name[0] (a datamember) of object C, then same change must reflect in object B (due to shallow copy being created) but its not showing that.

hi @vishaaltiwari1999

shallow copy created when default copy constructor is called
but you have make your ones so it is not calling default constructor
and in your copy constructor you make a mistake so it is giving segmentation fault

to get correct output

  1. first remove your copy constructor (line 19-24)
    then see ouput boths name will change

now add your own copy constructor with some change
modified copy constructor

 car (const car &x)
    {
        int l=strlen(x.name)+1;
        name = new char[l]; 
        strcpy(name,x.name);
        price=x.price;
        model=x.model;
    }

after that deep copy will be created

i hope this help
