Is It You, Cody?

by CodeChum Admin

Can you identify if Cody's name is spelled right? If so, then make a program that accepts four one-letter strings separated by space and print "Correct" if the inputted strings, combined in order, spell the name Cody correctly. If not, print "Wrong". It doesn't matter if it's in uppercase or lowercase, as long as it's spelled correctly, it's considered correct.

Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient the following data should be entered: i. The number of days spent in the hospital ii. The daily rate iii. Charges for hospital services (lab tests, etc.) iv. Hospital medication charges. If the patient was an out-patient the following data should be entered: i. Charges for hospital services (lab tests, etc.) ii. Hospital medication charges. The program should use two functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for out-patient data. Both functions should return the total charges. Input Validation: Do not accept negative numbers for any information.
