b. Drawing a polygon
Now that you can draw a circle, the next step is to draw a polygon inside the circle. Write a function
DrawPolygon (N). The points of a N-sided polygon should be at angles 2π/N. You should add an extra
point at the end so your polygon looks closed.
Use your function to draw a 5-sided polygon (after drawing the circle):
DrawCircle()
DrawPolygon (5)
plt.show()
Write below your function to draw a N sided polygon and then use it to draw a 5-sided polygon. You
can use dTheta = 2*np.pi/N in your function.

# ANSWER ME
Answer (end)
I am doing a word guessing game where I have created a function that shuffles a word randomly. However, I want to create a function that will act as a clue when the user presses it; it will display the first word of the jumbled word.
For example, if the word is - friends, The Jumbled word would be - siedfrn, with the function I already made.
However, in order for users to get some help, they can press a number(4), and the needed function will result in the output to be- fiedsrn.
Define stubs for the functions get_user_num() and compute_avg(). Each stub should print "FIXME: Finish function_name()"
followed by a newline, and should return -1. Each stub must also contain the function's parameters.
Sample output with two calls to get_user_num() and one call to compute_avg():
FIXME: Finish get_user_num( )
FIXME: Finish get_user_num()
FIXME: Finish compute_avg()
Avg: -1

- C languagearrow_forwardA company wants to transmit data over the telephone but is concerned that its phones may b tapped. It has asked you to write a program that will encrypt the data so that it may be transmitted more securely. All the data transmitted is 4 digit integers. Your program should read a four digit integer entered by the user and calls a function encrypt which takes four digits as arguments and encrypt it as follows . Replace each digit with the result of adding 4 to the digit and getting the remainder after dividing the new value by 10. . Calls another function swap which swaps the first digit with the third, and second digit with the fourth using pass by reference. Then it prints the encrypted integer.arrow_forwardA natural number is prime if it is greater than 1 and has no divisors other than 1 and itself.

- Step 3. Your starting code has a function readNames returns an array of student names. The temporary code you were given always returns the same five names shown above (Ava, Ben, ...). Now you will change this function so that it reads from StdIn an integer N 2 0, followed by N names. You can assume that after N, the input will always be exactly N names, each on one line that could be read using the function StdIn.readString . There are several example data files in the directory that conform to this specification. For example names3.txt contains 3 names (Ava, Ben and Carol). Your function should return an array containing those N student names. For example, if you provide the file names3.txt on StdIn your version of readNames would return the three names in that text file, and the output would be: $ java-introcs ZoomRooms greedy 3 < names3.txt Room: 0 Ava Ben Carol Room: 1 Note that with the code we have so far we will always print out exactly two rooms, regardless of the number of…arrow_forwardThis is not a graded question so please don't disregard it as if it is.Thank you in advance professor! Note: This is a THEORETICAL QUESTION and no code should be used for solving it.arrow_forwardThe use ofcomputers in education is referred to as computer-assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. These two rand generated integers must be pass to the function named “ResultChecking”. The function should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, the function will return 1 or true if it is false the function will return 0 to false. In the main you must display the message "Very good!" if the answer is correct and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. The function “ResultChecking” should be called once when the application begins execution and each time the user…arrow_forward

If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A = -1. The value of A should be returned by the function. Test the function by passing various data to it and verifying the returned value.arrow_forward1.
