Load the Operator Stack to Call the Function ()() in C ++

Load the Operator Stack to Call the Function ()() in C ++ is easier to understand when the core ideas are paired with practical examples. The sections below explain the topic clearly, highlight useful steps, and point out details that can prevent common errors.

C ++ function call () can be overloaded for objects of class type. When you overload (), you are not creating a new way to call a function. Rather, you are creating an operator function that can be passed an arbitrary number of parameters.

the example below illustrates how to overload the operator to call the function () 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 ; } // nap chong toan tu goi ham () KhoangCach operator ()( int x , int y , int z ) { KhoangCach K ; // bay gio, dat phep tinh bat ky K . met = x + y + 5 ; K . centimet = y - z + 20 ; return K ; } // 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 ( 24 , 36 ), K2 ; cout << "Khoang cach dau tien la: " ; K1 . hienthiKC (); K2 = K1 ( 15 , 15 , 15 ); // trieu hoi toan tu () cout << "n--------------------------n" ; cout << "Khoang cach thu hai la: " ; K2 . hienthiKC (); return 0 ; }

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