The Microsoft button was exclusively used in the 2007 versions of word, excel, powerpoint, access and outlook. It has all of the different options like to save, print, open ect. It was located in the top left hand corner of the screen. It looked a bit like this (see attachment).
Answer:
Commands: commands are also known as "programs" and the program is a set of rules that performs a specific task which is executed by a computer.
Unix is an operating system. that supports multi-tasking and multi-user functionality. Unix is most widely used in all forms of computing systems such as desktop, laptop, and servers. It provides a Graphical user interface similar to windows.
The Unix operating system there are various commands. The list of five Unix commands can be given as:
1) cal
2) date
3) banner
4) who
5) whoami
1)cal:
The cal command stands for calender. It displays the date.
Syntax:
$ cal
or
$ cal [[month] year]
Example:
$ cal 10 2019
2)date:
The date command stands for date and time. It displays the system date and time.
Syntax:
$date
or
$ date[+format]
Example:
$ date +%d/%m/%y
3) banner
The banner command stands for display the text in to a large size.
Syntax:
$banner message
Example:
$banner Unix
4) who
The who command stands for display the list of users currently logged in.
Syntax:
$who
or
$who [option] … [file][arg1]
Example:
$who
5) whoami
The whoami command stands for display the user id of the currently logged-in user.
Syntax:
$whoami
Example:
$whoami
Explanation:
1)cal command display the current month and year.
2)date command display system date and time.
3)banner command display text in large size.
4)who command display the user name who currently login.
5)whoami command display user id.
Answer:
17.0
Explanation:
after first loop numA = 0.0 + 2 = 2.0
after second loop numA = 2.0 + 5 = 7.0
after third loop numA = 7 + 10 = 17.0
Answer:
The code solution is written in Java.
- import java.util.Scanner;
-
- public class TestScore {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
-
- System.out.print("Please enter first score: ");
- double firstScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(firstScore));
-
- System.out.print("Please enter second score: ");
- double secondScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(secondScore));
-
- System.out.print("Please enter third score: ");
- double thirdScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(thirdScore));
-
- System.out.print("Please enter fourth score: ");
- double fourthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fourthScore));
-
- System.out.print("Please enter fifth score: ");
- double fifthScore = input.nextDouble();
- System.out.println("Grade: " + determineGrade(fifthScore));
-
- System.out.println("Average score: " + calcAverage(firstScore, secondScore, thirdScore, fourthScore, fifthScore));
-
- }
-
- public static double calcAverage(double score1, double score2, double score3, double score4, double score5){
- double average = (score1 + score2 + score3 + score4 + score5) / 5;
- return average;
- }
-
- public static String determineGrade(double score){
- if(score >= 90){
- return "A";
- }
- else if(score >= 80 ){
- return "B";
- }
- else if(score >=70){
- return "C";
- }
- else if(score >=60){
- return "D";
- }
- else{
- return "F";
- }
- }
- }
Explanation:
Firstly, create the method, <em>calcAverage()</em>, that takes five test scores. Within the method, calculate the average and return it as output. (Line 33 - 36)
Next, create another method, <em>determineGrade()</em>, which takes only one score and return the grade based on the range of the score. (Line 38 -54)
Once the two required methods are created, we are ready to prompt use for input five test scores using Java Scanner class. To use get user input, create a Scanner object (Line 7). Next, use getDouble() method to get an input score and assign it to variables firstScore, secondScore, thirdScore, fourthScore & fifthScore, respectively. Once a score input by user, call determineGrade() method by passing the input score as argument and immediately print out the return grade. (Line 9 - 27)
At last, call calcAverage() method by passing the first test score variables as argument and print out the returned average value. (Line 29).
