Write a c program to run on ocelot to read a text file and print it to the display. it should optionally find the count of the number of words in the file, and/or find the number of occurrences of a substring, and/or take all the words in the string and sort them lexicographically (ascii order). you must use getopt to parse the command line. there is no user input while this program is running. usage: mywords [-cs] [-f substring] filename • the -c flag means to count the number of words in the file. a word would be a series of characters separated by spaces or punctuation. a word could include a hyphen or a single apostrophe. • the -s option means to print the words in the file sorted by ascii order. • the -f option will find the number of occurrences of the given substring. • you may have any number of the flags included or none of them. • the order they should be run would be: -s first, -c second, and -f third. • output should be well formatted and easy to read. the source file should have your name & pantherid, a description and it should have the affirmation of originality included in a comment at the top. code should be nicely indented and commented. create a simple makefile to compile your program into an executable called mywords.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
