Problem This is an extension to Homework 7 that calculates health information. In addition this will allow the user to re-enter the correct input when erroneous input is detected. Also, this program will allow the user to enter information for multiple persons. Remember that HW07 had the program terminate if the user entered an invalid input such as a weight less than 100 pounds, an age less than 18, etc. For Homework 8, if the user enters invalid data to a prompt, print an appropriate error message and prompt the user again to re-enter the information. See the Sample Execution below. After completing the calculation for one person, prompt if the user wishes to continue. The user must be prompted to enter the word "Yes" or the word "No." In theory, the user must enter only one of these two words, or receive an error message to re-enter one of the two values. A common programming practice for Yes/No responses is to "short-cut" the response. After the user enters the response of "Yes" or "No" (string), use only the first character to make the decision. If the user enters "Yes," the decision will be based on the letter Y'; similarly with "No." To avoid issues with upper and lower case, change the character to upper case (or lower case if so desired; just be consistent) This brings up one other question: what if the user does not enter the letter ? or the letter The user could be prompted again, but you are to take an easier approach. If the user enters the letter?Y', the program will do another calculation. Any other input will halt the program with the message "Have a good day." Programming focus This program will require the use of loops Description: See Homework 7 for all of the formulas and rules for valid input. There is no need to change any of the formulas as Homework 8 focuses on the validation of the input
