All 4 problems can be solved in the same program. All 4 problem shoudl use a c-string (an array of characters). 

1. Declare a c-string of size 200. Read in a string of maximum size 180, terminated by the % character, from the user. Then, print the second half of the string. 

Sample Run:
Enter the string: Well, it’s no secret that the best thing about a secret is secretly telling someone your secret. Thereby adding another secret to their secret collection of secrets. Secretly%

The second half is: ur secret. Thereby adding another secret to their secret collection of secrets. Secretly

2. Print only the uppercase characters from the string you read in for the previous problem. 

Sample:
The uppercase charcaters are:
W T S

3. 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

4.  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.
