no Appropriate default constructor available in vc++

Question

I have a method Close() in a class called X. I want to use that function in some other class called Y. I have created an object for class A and I call that Close() function there. At that time I am getting an error "No Appropriate default constructor Available."

I have created it like this..

X x;  x.Close();

How can I solve this?

Answer 1

Either class X has no acceptable default constructor os some type used within method Close of class X has no default constructor.:) Either you should define the default constructor or use a constructor with parameters that is defined for the class.

I have a method Close() in a class called X. ... I have created an object for class A and I call that Close()

Also you need to put the place in order what is class X and what is class A.:)
