Exercise 21 - due at 11:59:00 PM EDT on Sunday 10/24/2021 Both problems can be solved in the same program 1. Read in a newline terminated string with a maximum of 90 characters from the user. Write a C++ function that would take this string as a parameter, count the number of alphanumeric characters in the string, and return the count. Sample Run: Enter a string: The quick brown fox jumps over the lazy dog 30 times. There are 42 alphanumeric characters 2. Read in a lengthy string(capacity 150 characters) delimited by '*'. This string could have newline characters in it. Pass this string into a function that will retrun the number of lines in the string. (Hint: count the number of '\n' characters). Sample run: Enter a string: Taco cat Blue Green Red Some text here This is another line. And another one* The text had 6 lines.
