A has a function fun() which B tries to overload as fun(int). Sounds simple and the program looks correct but it doesn’t compile. Have a look at http://codepad.org/NQ3JNuRr . Its hard to digest for it is an obvious code to compile in C++. The code listing is as below: #include<iostream> using namespace std; class A{ public: void fun(){cout<<"fun\n";} }; class B: public A{ void fun(int i){cout<<"funB\n";} }; int main() { B b; b. /2010/05/24/c-reference-not-to-be-confused-with-java/python/...-reference/ Mon, 24 May 2010 00:00:00 +0000 /2010/05/24/c-reference-not-to-be-confused-with-java/python/...-reference/ This program assigns a new object of class A to reference a. It looks as expected, reference changes to new object ( see line 23,24,25): #include <iostream> using namespace std; class A { string name; public: A(string n): name(n) { } A(): name("NO ONE") { } void print() { cout << "I am "<< name << "!"<< endl; } }; int main(int argc, char *argv[]) { A matrix = A("the matrix"); A &a = matrix; a.
