Plugged in i think is the answer
Answer:
"mmaBooks.Customers.Add(customer);" is a correct answer for the above question.
Explanation:
Missing information : The correct answer is missing in the question which is defined in the answer part.
- If a user wants to add any objects to any collection in the C# programming, then he needs to follow the "Entity_data_model_named. collection_name. ADD(object_name)" syntax. The above question also wants this type of statement.
- The option c states the same statements, but there is needs one statement to define the name of db or database models. But the option c does not hold the name of the database models. Hence it is not the correct answer.
- And the other options do not follow the syntax to add, hence others is also not a valid option.
<h2>Yes the swap method exchange parameter values if passed by reference or the value gets changed inside the function.</h2>
Explanation:
Since the program is not given, I will try to guide you about the mode of parameters.
The meaning of swap is interchanging the values. It can be done by using temporary variable or without using it (if the values are integers).
While passing the parameters, there are two ways, call by value/pass by value and call by reference/ pass by reference.
If call by value, then the value gets swapped only inside the function and will not reflected in the calling portion. Call by reference is other way round.
