Assignment Operator Overloading in C++

This C++ program demonstrates overloading of assignment (=) operator. The program defines a class, defines the assignment operator for the class, creates an instance of the class and demonstrates its use.

Here is the source code of the C++ program which demonstrates overloading of assignment (=) operator. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

```
```
#include <iostream>
```
```
using namespace std;
```

```
    public:
```
```
        Int(int ii = 0) : i(ii) { }
```

        Int operator=(const Int& ii) { i = ii.i; }

```
        int get() { return i; }

```

    cout << "a::i = " << a.get() << endl;

    cout << "b::i = " << b.get() << endl;

    cout << "After operation a = b" << endl;

```
    a = b;
```

    cout << "a::i = " << a.get() << endl;

    cout << "b::i = " << b.get() << endl;

```
}
```

$ a.out
Initial values
a::i = 10
b::i = 20
After operation a = b
a::i = 20
b::i = 20
