Question

GENERAL INSTRUCTIONS

1.              All requirements specified on page 64-67 of the course packet “2.5 Programming Assignment Submission Requirements” and “2.6 Flow Chart Symbols” should be followed.
2.              Plan the programs on paper before you attempt to write any programs (it will take less time to complete the assignment overall).
3.              Electronic version of your programs (the .m files you create) must be uploaded to Canvas. Attach multiple files to one submission. All files must be received by the beginning of class on the announced due date. Plan accordingly. Be sure to use the filename guidelines specified in the assignment guidelines handout.
4.              Reminder that this is (like all homework assignments) an individual homework assignment. You may discuss general programming methods with each other but your work must be completed independently (see syllabus for academic integrity reminder).

Comments about flowcharts

• You can use any software to make the flowchart (Word, Excel, Visio, draw.io or others), or you can draw it by hand. If you draw it by hand, you must use a straightedge or template to draw the shapes and lines.
• This video shows how to make a flowchart with MS Excel 2010 https://www.youtube.com/watch?v=R46sUoojjfM Some things to remember about flow charts:

• All flowcharts begin and end with a terminator symbol (start/stop or begin/end).
• The shapes in the flowchart are connected by arrows that show the flow of the program.
• Flowcharts use specific symbol shapes for input/output and for calculations/processes.

PROGRAM #1

Plan, write and execute a program that will have the user enter the tire pressure for all the tires on their vehicle. Your program will average the tire pressures and output the average pressure. You will need to do some research regarding the units that are typically used for tire pressure and be sure to instruct the user to enter a number with the appropriate units. Use formatted output. Report the average pressure to one decimal place. Have the command prompt show two lines below your output. Your output may look something like this (note: the units shown in the example are nonsense units. You should do some research to know what the correct units should be.)

The average tire pressure is 245.5 bubbles.

PROGRAM #2

Plan and write an Octave program that will have the user enter the coordinates of two points that are on a line. Your program needs to determine the equation of the line. Display for the user the equation of the line in slope-intercept form.

                Your two points (3,15) and (6,-9) form a line.

       The equation of your line is: y = -3.000x + 9.000

The slope and the y-intercept should be displayed in the equation to three decimal places. You can assume that the user will not enter two points that make a vertical line. Your program should handle all other possible lines.

Answer 1

Code for question 1:

import java.util.*;

class Main {

public static void main(String[] args)

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter the no. of tyres");

int noOfTyres=sc.nextInt();

double[] pressure=new double[20];

double press=0;

for(int i=0;i<noOfTyres;i++)

{

System.out.println("Enter the pressure of tier "+(i+1)+" in kPa");

pressure[i]=sc.nextDouble();

press=press+pressure[i];

}

double Avgpressure=press/noOfTyres;

System.out.format("The average tyre pressure is %.1f kPa",Avgpressure);

}

}

The code Snippet and output :
