#include <iostream>
#include <iomanip>
using namespace std;
class A {
public:
int _i;
A(int i) : _i(i) { }
virtual A &operator=(A const &other) {
if (this!=&other) {
_i = other._i;
}
return *this;
}
virtual A operator+(A const &rvalue) {
return A(_i + rvalue._i);
}
virtual void print() {
cout << "A(_i=" << _i << ")";
}
};
class B : public A {
public:
int _j;
B(int i, int j) : A(i), _j(j) { }
virtual void print() {
cout << "B(_i=" << _i << ", _j=" << _j <<")";
}
};
int main() {
A a1(5), a2(3);
a1.print();
cout << " + ";
a2.print();
cout << " = ";
A a3 = a1 + a2;
a3.print();
cout << endl;
B b1(5,3), b2(3,5);
b1.print();
cout << " + ";
b2.print();
cout << " = ";
// this works, although (b1+b2) returns an A since it uses
A's operator+
(b1+b2).print();
// this does not work: no conversion from A to B, i.e.
operator= not inherited
// B b3 = b1 + b2;
// b3.print();
cout << endl;
return 0;
}

What is abstraction encapsulation?
What is cohesion in oop?
assume the program must insert 4 elements from the key board and then do the following programs.sequential search(search one of the elements),using insertion sort(sort the element) and using selection sort(sort the element).
i=20;k=0;
for(j=1;k-i;k+=j<10?4:3)
{
cout< Is html an oop? write a code for this. serial_number contained in the
header of the file will be read , if this serial number is
less than a previous serial number within a successfully
processed file, or is the same as another serial number
within a successfully processed file, or if the field
contains anything other than 7 digits, then the file must
error with the reason ‘Invalid SERIAL_NUMBER’. Can we create object of abstract class? What is the renewal class? i got a backdoor offer in process global,Bangalore..Can i
work with it? What is basic concept of oop? i am getting an of the type can not convert int to int *.
