Searching an Array for an Exact
Match
The data file provided for this lab includes the input
statements and the necessary variable declarations.
You need to use a loop to examine all the items in
the array and test for a match. You also need to set
a flag if there is a match, and then test the flag
variable to determine if you should print the "Not a
city in Michigan" message. Comments in the code
tell you where to write your statements.
