Load the stack of assignment operators in C ++

You can overload the assignment operator (=) as you can with other operators in C ++ and it can be used to create an object like copying constructors.

The following example illustrates how to overload the assignment operator in C ++:

 #include using namespace  std ; class KhoangCach { private : int  met ; int  centimet ; public : // phan khai bao cac constructor can thiet KhoangCach (){  met  = 0 ;  centimet  = 0 ; } KhoangCach ( int  m , int  c ){  met  =  m ;  centimet  =  c ; } void operator =( const KhoangCach & K  ) {  met  =  K . met ;  centimet  =  K . centimet ; } // phuong thuc de hien thi khoang cach void  hienthiKC () {  cout  << "nDo dai bang m la: " <<  met  << "nVa do dai bang cm la: " <<  centimet  <<  endl ; } }; int  main () { KhoangCach  K1 ( 23 , 16 ),  K2 ( 15 , 46 );  cout  << "Khoang cach dau tien: " ;  K1 . hienthiKC ();  cout  << "n-------------------n" ;  cout  << "Khoang cach thu hai:" ;  K2 . hienthiKC (); // su dung toan tu gan  K1  =  K2 ;  cout  << "n-------------------n" ;  cout  << "Khoang cach dau tien: " ;  K1 . hienthiKC (); return 0 ; } 

Compiling and running the above C ++ program will produce the following results:
