Write a program IN C that reads all integers that are in the range of 0 to 100, inclusive from an input file named: a.txt and counts how many occurrences of each are in the file. After all input has been processed, display all the values with the number of occurrences that were in are in the input file.

Note: The program ignores any number less than 0 or greater than 100.

Note: Do not display zero if a number is not in the file.

Hints: An array of size 101 is good enough. A number in the file plays the role of an index.

For example: Suppose the content of the file: a.txt is as follows:
99 2 99

3

-12 80 12 33

3 99 100 1234 84

The display output is:
2 has occurred: 1 times

3 has occurred: 2 times

12 has occurred: 1 times

33 has occurred: 1 times

80 has occurred: 1 times

84 has occurred: 1 times

99 has occurred: 3 times

100 has occurred: 1 times

Note that this is just a sample dialog. Your program should work for any number of data values and you MUST match the sample dialog as well.

Visitors at a science museum are invited to sit in a chair to the right of a full-length diverging lens (f1 = -3.30 m) and observe a friend sitting in a second chair, 1.80 m to the left of the lens. The visitor then presses a button and a converging lens (f2 = +4.50 m) rises from the floor to a position 2.10 m to the right of the diverging lens, allowing the visitor to view the friend through both lenses at once. Find (a) the magnification of the friend when viewed through the diverging lens only and (b) the overall magnification of the friend when viewed through both lenses. Be sure to include the algebraic sign (+ or -) with your answers.
