Write a program that allows the user to input any number of hexadecimal characters. Sum the values and display the sum as a hexadecimal value.

Treat each single inputted character as a separate value. Within the loop, convert each character entered into its decimal equivalent. Display the original hex value and the corresponding decimal value. For example, if the user inputs F, 15 would be displayed as the decimal equivalent. Create a state-controlled loop structure. After all values are entered, display the sum of values entered in both hexadecimal and decimal notation.
