/* LAB: Searching for an element in an array:

STEP 1: Define an array and read in values.
STEP 2: Ask the user for a single value.
STEP 3: Tell the user whether the number appears in the array.
STEP 4: Tell the user the index of the that number in the array.

for example:
define an arrray with SIZE=300
read in the following values: 4 8 26  24  37
read in a number: 8
tell the user: YES! 8 is in location 1 of the array.

For the advanced student OR any student who wants to practice:
Modify pgm28 to work with files.
