Can I access a variable in a function which is in a class through an object?

class A 
{ 
int a;
double b;
public:
A(){a=20;B=78.438;}
void data()
{ int num1; num1=a;}
}

I have above CPP code. Can I access 'num1' variable using object of class A type?

I think this question is different than "How to access variables defined and declared in one function in another function?".

Because here I want to access variable , which is in the function, which is a member of the class A. And I want access through object of class A type.

No, you cannot.num1 is declared inside a function data() so you have no access to it through object of type A. You would have to move declaration of int num1; to class body.:

class A 
{ 
  int a;
  double b;
  public:
  int num1;
  A(){a=20;B=78.438;}
  void data()
  {  
    num1=a;
  }
}

now you can write:

A a;
a.num1 = 1;
