Question

Can someone explain to me the (*this) pointer and demonstrate how it would be used as far as an object calling another object of the same class. What I don’t understand is how you would refer to two numbers in a member function of different 2 different objects of the same variable name. For example, multiplying two numbers.

a.Multiply(b);
//....
Numbers::Numbers Multiply(Numbers auggend)
{
}

Answer 1

this pointer:

The member functions of every object have access to a pointer named this,which points to the object itself.When we call a member function,it comes into existence with the value of this set to the address of the object for which it was called.Using a this pointer any member function can find out the address of the object of which it is a member.It can also be used to access the data in the object it points to. Example:

void setdata(int ii)
{
   i=ii;         // one way to set data
   this->i=ii;   // another way to set data
}
