Sure, I can help you with that.

To implement an interface with two abstract methods by a lambda expression, you can use the auto keyword. The auto keyword tells the compiler to infer the type of the lambda expression.

The following code is an example of how to implement an interface with two abstract methods by a lambda expression:

C++

// Define an interface with two abstract methods.
interface IMyInterface {
  void Method1();
  void Method2();
};

// Implement the interface with a lambda expression.
auto myInterface = []() {
  // Implement Method1().
  void Method1() {
    cout << "Method1()" << endl;
  }

  // Implement Method2().
  void Method2() {
    cout << "Method2()" << endl;
  }
};

// Call the methods of the interface.
myInterface.Method1();
myInterface.Method2();

In this code, the myInterface variable is a lambda expression that implements the IMyInterface interface. The Method1() and Method2() methods of the myInterface variable are implemented by the lambda expression.
