Prompt and read the monthly salary of the salesperson (double), the number of years he or she has worked (int), and total sales made (double). Your output will be the base salary, the bonus, and the total salary. Specifications . Comment all your variables and parts of code that perform calculations, input, and output, etc. Give your variables meaningful names . Variables must be declared with the correct type . Use constants in your program rather than use literals . Your program needs to re-prompt if input is not a valid number or if the amount entered is negative (or if the salary is too high, greater than ot equal to S1,500.00) All decimals need to formatted to two decimal places and all the output must be nicely aligned, refer to the sample output sample output your program, if they enter a lower case or upper case n then stop the program, if they don't enter y .Only output the bonus and the total after bonuses if some bonus can added to the salary, refer to the . You need to ask the user if they wish to continue, if they enter a lower case or upper case y, then rerun or n you need to re-prompt until a y or n is entered
