Ur program is to prompt the user for: - the book's 10 digit ISBN number (store as a string) - the list price per copy - the expected class enrollment - code of 'R' for required text or code of 'S' for suggested text - code of 'N' for a newly suggested text or code of 'C' for an old(repeated) text that has been used the previous quarter CALCULATE: Calculate the number of copies needed and the profit if the store pays 80% of list price, book store's cost, (use global #define macro for this). For the number of books to order, round to the nearest whole book quantity. Use one function to calculate number of books, one function to calculate the profit, and one function to output. OUTPUT, A sample run might look like this: Enter book number: 0755798652 Enter price per copy: 34.98 Enter expected class enrollment: 31 Enter 'R' if required or 'S' if suggested: r Enter 'N' if new or 'C' if not a new text: C ISBN: 0755798652 Copies Needed: __ Profit: $ THEME ISSUES ( what you have learned and to be applied in this lab): Functions (pass by value), if Constructs, character type, rounding
