Allow the user to enter only the first 4 letters of the last name and the first letter of the first name, they should be able to get the right author. Ask the user to input a percentage and calculate the new discounted price based on the current retail price minus this percentage. Round the result to cents (two decimals). For your example query, assume the user wants to discount the price of James Patterson books by 20%. Please, check your lab work for Chapter 10. We covered a similar query but without the use of substitution variables.
