A small startup software developer company needs to create a program that will calculate the pay of its employees. For the third version of the program, the company wants the program to accept an employeeâ??s name, the number of hours that the employee worked, and the hourly pay rate. The program will then calculate the gross pay, display the employeeâ??s name, number of hours worked, pay rate, and gross pay, but also calculate and display the net pay of the person after taxes have been calculated and deducted. The user will then be able to continue calculating the pay for additional employees until the user decides to stop. The user will then be able to continue calculating the pay for additional employees until the user decides to stop or until the maximum number of employees is reached. Create gross pay and net pay functions, and provide user input validation to check for a valid user name. Hours worked is between 0 and 80 hours, and the hourly wage is between $8.95 and $50.
Modify the Pseudocode below to Include the following:
Modify this Pay Calculator design to include a user-defined function to calculate the gross pay.
Modify this Pay Calculator design to include a user-defined function to calculate the net pay.
Modify this Pay Calculator design to include an input validation loop to ensure that the user provides a valid employee name (non empty); otherwise, the pay is not calculated. If the user decides not to provide an employee name, program will move to the next employee.
Modify this Pay Calculator design to ensure that the hours that an employee works is greater than 0 and less or equal to 80. If the hours worked are not valid, an error message shall be supplied to the user and the pay calculation will not be performed until the valid rate is provided. If the user decides not to provide a valid value, program will move to the next employee.
Modify this Pay Calculator design to ensure that the hourly pay rate is greater than or equal to $8.95 and less than $50. If the hourly rate is not valid, an error message shall be supplied to the user and the pay calculation will not be performed until the valid rate is provided. If the user decides not to provide a valid value, program will move to the next employee.
Complete a desk check of all algorithms, and modify the analysis and design to correct any errors.
