प्रश्न
Answer the question after going through the following class.
class Book {
int BookCode ; char Bookname[20];float fees;
public:
Book( ) //Function 1
{ fees=1000;
BookCode=1;
strcpy(Bookname,"C++"); }
void display(float C) //Function 2
{ cout<<BookCode<<":"<<Bookname<<":"<<fees<<endl; }
~Book( ) //Function 3
{ cout<<"End of Book Object"<<endl; }
Book (intSC,char S[ ],float F) ; //Function 4
};
In the above program, what are Function 1 and Function 4 combined together referred to as?
उत्तर
Constructor overloading (function 1 and function 4 are constructors with different signatures in the class book).
