This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width.(1) Modify the given program to use a loop to output an arrow base of height arrowBaseHeight. (1 pt)(2) Modify the given program to use a loop to output an arrow base of width arrowBaseWidth. Use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow base. (1 pt)(3) Modify the given program to use a loop to output an arrow head of width arrowHeadWidth. Use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow head. (2 pts)(4) Modify the given program to only accept an arrow head width that is larger than the arrow base width. Use a loop to continue prompting the user for an arrow head width until the value is larger than the arrow base width. (1 pt)while (arrowHeadWidth <= arrowBaseWidth) { System.out.println("Enter arrow head width: "); arrowHeadWidth = scnr.nextInt(); } Example output for arrowBaseHeight = 5, arrowBaseWidth = 2, and arrowHeadWidth = 4:Enter arrow base height: 5 Enter arrow base width: 2 Enter arrow head width: 4 ** ** ** ** ** **** *** ** * import java.util.Scanner;public class DrawHalfArrow { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int arrowBaseHeight = 0; int arrowBaseWidth = 0; int arrowHeadWidth = 0; System.out.println("Enter arrow base height: "); arrowBaseHeight = scnr.nextInt(); System.out.println("Enter arrow base width: "); arrowBaseWidth = scnr.nextInt(); System.out.println("Enter arrow head width: "); arrowHeadWidth = scnr.nextInt(); // Draw arrow base (height = 3, width = 2) System.out.println("**"); System.out.println("**"); System.out.println("**"); // Draw arrow head (width = 4) System.out.println("****"); System.out.println("***"); System.out.println("**"); System.out.println("*"); return; }}

In this assignment, you are asked to complete a program that gets a file name (and path) as its only command-line argument and shuffles the file content randomly using low-level I/O functions open, read, write, and lseek. Here is the incomplete program: (See Attached Image. I could not copy paste the code, so I have to screenshot, sorry.)As you see, the program first opens a file, say “io.txt”, using “O RDWR” mode since it’s supposed to both read the file and write into it. Then, using lseek, it finds the number of bytes/characters stored in the file. If we assume that originally, the file “io.txt” contains the sequence of characters a1, a2, . . . , an, your task is to complete the implementation of main function so that the program manipulates the file in a way that after termination of the program, the file contains the same same sequences of characters, but with a random permutation: aπ1 , aπ2 , . . . , aπn where π1, π2, . . . , πn is a random permutation of numbers 1, 2, . . . , n. For example, if the file content is originally “eat”, after running the program, the file content must be one of the following six words: eat, eta, ate, aet, tea, tae Of course, a correct implementation will output each word with an equal chance of 1/6. Also, a correct implementation should not assume any upper-bound for the file size. As the only deliverable of this assignment, you need to submit a .c file.

For the final assignment, summarize the site requirements and/or any challenges (changes to the topology as you detailed in Assignments 1 and 2) you are attempting to overcome. You should also provide an updated overall site topology based on your design.This solution should be comprehensive, and the approach should be justified. Configurations of technologies should be written out to help guide the systems administrators with implementation. In some cases, you may find it necessary to implement additional cabling, which can be done by adding to the supplied topology. Any adjustments to the sites’ topology should be documented and supplied with your submission.Use the Final Network Proposal Template to record your work.How Will My Work Be Evaluated?1.2.2: Employ a format, style, and tone appropriate to the audience, context, and goal.1.3.3: Integrate appropriate credible sources to illustrate and validate ideas.2.1.3: Explain the significance of the issue or problem.2.3.1: State conclusions or solutions clearly and precisely.2.3.2: Incorporate relevant evidence to support the position.2.3.3: Explain inferences and deductions that follow logically from the evidence provided.10.1.3: Define the specifications of required technologies.12.1.3: Communicate policies, processes, and/or procedures to stakeholders.13.1.1: Create documentation appropriate to the stakeholder.All my assignments are attached in order to complete this assignment.
