3.4. Overloading a function call operation

This is a '()' operation. It is a binary operation. The first operand is usually a class object, the second is a parameter list.

Example.

class matriza // two-dimensional array of real numbers

{

...

public:

...

double operator () (int, int); // access to matrix elements by index

};

double matriza :: operator () (int i, int j)

{...}

void main ()

{class matriza a;

...

k: = a (5,6);

...

}
