Exercise # 1 : The 10 digits are spelled out respectively as follows: "Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", and "Nine". Write a program that prompts the user to enter a one digit positive integer and prints the number of characters required to spell out the integer. For example, if the integer is 7 then it is spelled "Seven" which requires 5 characters. Sample input/ output: Enter a one digit number: 8 8 has 5 characters
