Step by step
Solved in 2 steps
- A class that has only pure virtual functions is known as a(n)_ Write your answer here.This is in c++. Create a class of function objects called StartsWith that satisfies the following specification: when initialized with character c, an object of this class behaves as a unary predicate that determines if its string argument starts with c. For example, StartsWith(’a’) is a function object that can be used as a unary predicate to determine if a string starts with an a. So, StartsWith(’a’)("alice") would return true but StartsWith(’a’)("bob") would return false. The function objects should return false when called on an empty string. Test your function objects by using one of them together with the STL algorithm count_if to count the number of strings that start with some letter in some vector of strings. So basically, I want a class that returns true or false based on if the name that is typed starts with the character that I put down.All of the functions in the class A(n)_ are virtual functions. Let us know what you think by filling in the gaps.
- A C++ assignment Implement the GradedActivity class. Copying from the pdfs is fine. Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature: void Assignment::set(int, int, int) Create a main program which instantiates an Assignment, asks the user for its functionality, efficiency, and style scores, and prints out the score and letter grade for the assignment. ___________________________________________________ Examples from the pdfs: d PassFailExam::set(int q, int m, int p) { double numericScore, pointsEach; numQuestions =…Write a simple function template for predicate function isEqualTo that compares its two arguments of the same type with the equality operator (==) and returns true if they are equal and false otherwise. Use this function template in a program that calls isEqualTo only with a variety of fundamental types. Now write a separate version of the program that calls isEqualTo with a user-defined class type, but does not overload the equality operator. What happens when you attempt to run this program? Now overload the equality operator (with the operator function) operator==. Now what happens when you attempt to run this program?Give an example of how the background process of invoking inline functions is different from that of calling a standard function, and explain how the difference came to exist. In addition, give an example of how the difference was brought about.
- To overload the pre-increment operator for a class as a member function, how many arguments are required? b.When overloading the pre-increment operator for a class as a friend function, how many arguments are required?In C++,Create a class Test with two private integer data members: x and y and onemember function: getdata() for taking input of x and y. Create two nonmember friend functions: task1() and task2() to class Test, such as task1()is displaying squares of integers from 1 to x and task2() is finding the sumof all integers from 1 to y.In C++ programming language. Write a statement that declars sObj to be an object of type strange such that the private member variables a and b are of type int. Write a statement that declares sObj that shows the declaration in the class strange to overload the operator = = as a member function. Assume that two objects of type strange are equal if their corresponding member variables are equal. Write the definition of the function operator == for the class strange, which is overloaded as member function
- Suppose that the binary operator + is overloaded as a member function for the . How many parameters does the function operator+ have? (5, 6) Suppose that the binary operator && is overloaded as a nonmember function for the . How many parameters does the function operator&& have? (5,6)Suppose that you have the declarations of Exercise 7. Write the definitions of the member functions of the classes circle and cylinder. Identify the member functions of the class cylinder that overrides the member functions of the class circle. (2, 3, 4)Is it possible to call a class function Object() { [native code] } from within another function Object() { [native code] }?
