C++ Programming: A Practical Approach

192 C++ Programming

void display(Test & x1) { cout << x1.i << endl; } // Object of Test class is passed by reference

int main()

{

Test t1(10.1);

display((float)10.1); // Think whether 10.1 automatically gets converted into object of Test class

};

Output

Compilation error

Implicit conversion will not happen in this case as 10.1 is explicitly specified as float.

4.9 Points to Remember

(i) Operator overloading is used to achive static polymorphism because operators can be

used with objects in the same manner operators are used with varibles of built-in data

types.

(ii) To overload the operator, it is necessary to write the operator function.

(iii) ...
