Which of the following regarding R-values in C++17 is/are true? Select all that apply. Pick ONE OR MORE options Integer literals and string literals are both natively R-values An R-value can be passed to a function that accepts a constant L-value reference, but not to a function that accepts a non-constant L-value reference Any time two ampersands (&&) appear in syntactically valid C++17 code, they indicate the presence of an R-value reference For a given type ~T~, constructing an instance of ~T~from an R-value reference is always strictly more efficient than constructing an instance of ~T~ from an L-value reference It is possible to restrict a class's custom call operator such that it may only be used on instances of the type that are R-

Please answer in C++ Define a structure called Date with month, day and year as its only data members, Time with hour and minute as its only members and Event with desc (a c-string for description of maximum size 80), date (of type Date) and time (of type Time). Write a readEvents() function that will keep asking the user if he or she wants to add a new event. As long as the user answers with a 'y' or 'Y', allocate memory dynamically for an Event structure, storing the pointer returned by new in the array of Event pointers and then read the Event data from the keyboard and store them in the Event just created. Dates should be entered like 5/21/20 and times as 10:15. When finished entering the Events, the function will return the number of Events entered. Write a sort-desc() function to sort the Events by their description by rearranging the pointers (rather than the structures), by passing it the array of pointers and the number of Events created. Use a swapPtrs() function to swap…
Write a value function in a C++ program that has two double parameters, calculates their difference, and returns the absolute value of the difference?
Set-up and implementation code for a void function MaxYou are not required to write a complete C++ program but must write and submit just your responses to the four specific function related questions below: QC1: Write the heading for a void function called Max that has three intparameters: num1, num2 and greatest. The first two parameters receive data from the caller, and greatest is used to return a value as a reference parameter. Document the data flow of the parameters with appropriate comments*. QC2: Write the function prototype for the function in QC1. QC3: Write the function definition of the function in QC1 so that it returns the greatest of the two input parameters via greatest, a reference parameter. QC4: Add comments to the function definition* you wrote in QC3 that also states its precondition and postcondition.
Create a function in C language that takes two integers x, and y as the parameters and returns the sum and the absolute difference of both the numbers but the return type of the function should be void. You can add extra parameters to the function but the function should not return anything and should send the required values as well. Test your function for the numbers 10, and 5 inside the main function.
Write a C++ function add_strings that takes two parameters of type string and returns the concatenation of the two parameters.

Define a struct fruitType to store the following data about a fruit: Fruit name (string), color (string), fat (int), sugar (int), and carbohydrate (int). Declare a variable of type fruitType to store the following data: Fruit name—banana, color—yellow, fat—1, sugar—15, carbohydrate—22. Write a C++ function, getFruitInput to get and store data into a variable of fruitType. Write a C++ function, printFruitInfo to output data stored into a variable of fruitType. Use appropriate labels to identify each component. Test your solution by calling all funtions.
