11.6 Lab Week 8: Message Encoder (1) Prompt the user to enter a string of their choosing (up to 100 characters long, which could include whitespaces). Then, output the string to the screen. (1 pt) (2) Complete the getNumAlpha0 function, which returns the number of letters in the user's string. (1 pt) (3) In main0, call the getNumAlpha0 function and then output the returned result. (1 pt) (4) Complete the encodeChar0 function, which returns the character stored in replaceChar if thisChar matches thatChar. Otherwise, the function returns the character stored in thisChar. (1 pt) (5) Complete the encodeString0 function, which should loop through the characters in usrStr making the following changes if necessary: replace any numeric digit (0-9') with #. replace the upper case letter 'O' with the number 0 . replace the upper case letter T' with the number '1 replace the upper case letter Z' with the number 2 replace the upper case letter 'E with the number 3 replace the upper case letter H' with the number'4 replace the lower case letter's' with the number 5 replace the lower case letter 'b' with the number 6 replace the upper case letter L with the number 7 replace the upper case letter 'B' with the number 8 replace the lower case letter 'g' with the number 9 All but the first replacement should be done by calling the encodeCharO function for each. (1 pt) (6) In main0, call the encodeString0 function and output the encoded string. (1 pt) Sample Input/Output: Enter a me 3 3 age : THE Answer t Life is 42 and big BIG Z003! You entered: THE Answer t Life is 42 and big BIG Zoos! Number of characters: 46 Number of letters: 30 Use the template provided. Do not change the function definitions. Simply fill in your code without changing the template Hard coding output to match test cases will automatically result in a zero on this assignment. The remaining 4 points will be for proper header, comments, variable names, and indentation (overall style)
