A summary for constructor, copy constructor and assign operator by myself ,right or ?

[flysnow]

When ,which funcition will be called ? how about priority?

eg:

 class T
{
 public :
    T( int );
   T();
};

T fun1()
{
   T t1;
  return t1;
}

void fun2(T t)
{
return ;
}

 T t;      //constructor 
 T t2 = t1 ; // copy constructor

  T t2 = 1  ; // constructor 

  t2 = t1 ;  // operator = 

  t2 = fun() ;// copy constructor and operator =

 fun2( t1) ; //copy constructor 
  

If you define operator = funciton to accept integer parameter, 
  
  t2 =  1 ; // call operator =

otherwise
  t2 = 1 ; //call constructor first and the call default operator =.

Any thing need to add ? pls give your comments ,Thanks!

You have not defined a copy constructor or a copy operator. You probably should if you want this to work. And as soon as you define a copy constructor, you should define a copy operator. It is considered as good coding practice.

class T
{
T(); //Default constructor
T(int); //Other constructor
T(const T& origin); //Copy contructor
T& operator=(const T& origin); //Copy operator
}

Anything else ?

Seems you've got everything in order with your comments. No precedence considerations that I can see. The other post finishes things out.
