+ empID: String firstName: String lastName: String payRate: Real Employee() SetEmpID(theID: String) SetFirstName(fName: String) SetLastName(IName: String) SetPayRate(testPay: Real) ValidString(testString: String, validMin: Integer, validLength: Integer, txtMSG: String): String ValidPay(pay: Real): Real DisplayEmployee(): String Employee Create an employee class based on this UML class diagram. The setters should prompt the user for the information to set the value of the instance variables. These are the validation rules: The ID has to be 4 characters long. If it is invalid the characters XXXX have to replace the invalid ID. The minimum length for a first or last name is 2 characters and the maximum length is 20 characters. If invalid the first or last name have to be replaced with XXXX. The pay rate has to be between 0 and 1000000. If invalid the pay rate has to be replaced with 0. Use the ValidString Function to validate the first name, last name and empID. The invalid message should include which item was incorrect. For example if the first name was incorrect it should display "Invalid first name. Set to XXXX" The Display Employee getter function should display all of the employee information. Create a program that uses the Employee class to create an array of employee objects based on the user's input. It should then display all of the employee data in the array. Example: Module main() Declare Integer employeeNo Display "How many employees do you want to enter?" Input employeeNo

This function will display the menu options that the user can choose (tocalculate perimeter or area of a triangle).

HW2b: R Exercises 1 Complete R Swirl 2 first! It will help you in this assignment! Instructions: Write one R script title HW26.R that contains your answers to problems 1- 5. At the top of the script write your name in a comment. Label each problem number using a comment and then type the code that solves that problem. Here's an example of the script format (where you should fill in the R code to solve each problem): 1 # Your Name # Assignment 3 , # Thu Feb 03 07:39:07 2022 2 4 5 # 1. 6 7 type the R commands solve problem 1 9. # 2. 10 11 type the R commands to solve problem 2 12 13 # 3. |14 15 etc. 1. What are the arguments for the Sequence Generation function seq() and give an example. Hint, use the methods you have learned to search for help in RStudio. 2.
