CS52-Assignment 4 Structs and Classes Solved

Problem 1                              Recursion                                                                           
Implement a program that lets the user enter a number and then prints the result calculated by the following function. Write a recursive function that n * n/3 * n/9 * …. where n/x 0 and n is a nonnegative integer. For example:

 

                        27: 27 * 9 * 3 * 1 = 729

          8: 8 * 2 = 16

          100: 100 * 33 * 11 * 3 * 1 = 108900

 

The function prototype should be: int recursive(unsigned int n);

 

Example:

            Input: 27

     Result: 729

      

 

Problem 2                              Date Class                                                                          
Design a class called Date. The class should store a date in three integers month, day, and year. Declare all member variables private and all member functions public. Each instance variable should have getter and setter functions to get and set each value. There should be three member functions to print the date in the following forms:

 

12/25/2018     December 25, 2018  25. December 2018 

Implement a program that lets the user enter a date using your Date class. The user enters a day, month and year. You will then create an object of the Date class passing in the three values to the constructor. Call each function to print the three different date forms as shown above.

 

 

 

                                                                             

Problem 3                              structs                                                                                 
 

Create a struct called Employee. The struct should have the following members:

•                  firstName:       string 

•                  lastName:       string 

•                  pay:     int      

Create a dynamic array of n employee variables where n is a number entered by the user. Then loop through the array and let the user input the data for each employee. Create a function that expects a pointer to the array as input and prints the elements in the array. Remember that arrays are passed by reference, that is, any modifications inside the function will be reflected in the caller’s array. 

Example:         Number of employees: 2

          Employee 1

          First Name: Allen

          Last Name: Harper

          Pay: 1000

          Employee 2

          First Name: John

          Last Name: Doe       Pay: 500

Employees: 

Name: Allen Harper (1000)

Name: John Doe (500)
