This application will provide the user with an option to choose to buy either New or Used trading cards. For either option, you will allow the user to enter in the number of cards to purchase, and then display the sales price. If the user enters an invalid input or option at any time, your application will inform the user that there is an error. Your program should do the following: 1.) Print a welcome message for your application. 2.) Prompt a menu prompt with two options: to purchase either New or Used trading cards. 3.) If the user chooses the New option, prompt the user how many cards they wish to purchase, and then calculate and display the total cost. Each new card should cost $0.85. 4.) If the user chooses the Used option, prompt the user how many cards they wish to purchase, and then calculate and display the total cost. Each used card should cost $0.57. 5.) If the user chooses an invalid menu option, inform the user of this error. 6.) If the user enters a numeric card quantity value that is 0 or less, inform the user that the entered value is too low. 7.) If the user enters a non-numeric value for card quantity, inform the user of this error.
