Code Explanation
First execute a do while loop as we want user to enter at least first character to check whether its upper case or not. If user enters exclamation character then this loop will terminate along with the program.
To check whether the entered character is upper case or not we will be using isupper(ch) method defined in cctype library.
If the character is upper case then if condition will show Ok by printing it using cout and this program will show nothing if the character is not upper case.
Sample Output
Enter Character: A
OK
Enter Character: b
Enter Character: c
Enter Character: d
Enter Character: E
OK
Enter Character: G
OK
Enter Character: F
OK
Enter Character: !

if arrivalHour < 0 or arrivalHour > 12:
print ("Invalid hour")
if arrivalHour == 0:
price = basePrice
else:
price = arrivalHour * incrementAmount
totalPrice = price + basePrice
if totalPrice > 53:
totalPrice = 53
