}

Explanation:

1. First, we include the iostream library, which allows us to use input/output functions in C++.

2. We define the main function, which is the entry point of our program.

3. Inside the main function, we declare three variables: number1, number2, and sum. These variables will be used to store the input numbers and the sum of the two numbers, respectively.

4. We use the std::cout object to display the message "Enter the first number: " to the console.

5. We use the std::cin object to read the input from the user and store it in the number1 variable.

6. We repeat steps 4 and 5 to get the second number from the user and store it in the number2 variable.

7. We calculate the sum of the two numbers by adding number1 and number2 together, and store the result in the sum variable.

8. We use the std::cout object again to display the message "The sum of the two numbers is: " followed by the value of the sum variable.

9. Finally, we return 0 to indicate a successful execution of the program.
