<h2>Answer:</h2>

141.95|212.95|312.95|10.95|

<h2>Explanation:</h2>

<em>Reformatting the code snippet and giving it line numbers;</em>

1.       var totals = [141.95, 212.95, 411, 10.95];

2.      totals[2] = 312.95;

3.      var totalsString = "";

4.      for (var i = 0; i < totals.length; i++) {

5.          totalsString += totals[i] + "|";

6.      }

Line 1 creates an array called totals with four elements.

     First element = totals[0] =141.95

     Second element = totals[1] = 212.95

     Third element = totals[2] = 411

     Fourth element = totals[3] = 10.95

Line 2 replaces the value of the third element <em>totals[2]</em> = 411 with 312.95.

     Therefore the array <em>totals = </em>[141.95, 212.95, 312.95, 10.95]

Line 3 creates an empty string called totalsString

Lines 4 - 6 create a for loop that cycles from i=0 to i<totals.length

       totals.length = 4 (which is the number of items in the array totals)

       This means that the loop cycles from i=0 to i<4

       During cycle 1 when i = 0, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[0] + "|"   //substitute the values

            totalsString = "" + 141.95 + "|"

            totalsString = 141.95|

       During cycle 2 when i = 1, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[1] + "|"   //substitute the values

            totalsString = "141.95|" + 212.95 + "|"

            totalsString = 141.95|212.95|

       During cycle 3 when i = 2, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[2] + "|"   //substitute the values

            totalsString = "141.95|212.95|" + 312.95 + "|"

            totalsString = 141.95|212.95|312.95|

       During cycle 4 when i = 3, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[3] + "|"   //substitute the values

            totalsString = "141.95|212.95|312.95|" + 10.95 + "|"

            totalsString = 141.95|212.95|312.95|10.95|

At the end of the execution, totalsString = 141.95|212.95|312.95|10.95|

Engineers involved in product design and manufacturing use computer-aided design/computer-aided manufacturing (CAD/CAM) systems,
stepan [7]

Engineers who are involved in product design and manufacture of computer-aided should have enough knowledge in circuit and auto cad electronic design.

<u>Explanation:</u>

He or she should have mother board, voltage in or out extra. Person who develops should enough knowledge on circuit design which capacitor, resistance and voltage and processor capacity.

Each design they have first simulates and tested and result should be recorded. On simulation test success design is made.

There is third party software also available for design the circuit and gives the tested results as report.

In this exercise you will debug the code which has been provided in the starter file. The code is intended to do the following:
abruzzese [7]

Answer:

The corrected code is as follows:

import java.util.Scanner;

public class U2_L4_Activity_Two{

public static void main(String[] args){

Scanner scan = new Scanner(System.in);

String str1 = scan.nextLine();

String str2 = str1;

str1 = str1.toUpperCase();

System.out.println(str1);

System.out.println(str2);

}

}

Explanation:

This corrects the scanner object

Scanner scan = new Scanner(System.in);

This line is correct

String str1 = scan.nextLine();

This copies str1 to str2

String str2 = str1;

This converts str1 to upper case

str1 = str1.toUpperCase();

This prints str1

System.out.println(str1);

This prints str2

System.out.println(str2);

What is the difference between concrete language and abstract language? give an example of each.
saul85 [17]

The difference between abstract language and abstract language is that abstract language is known through the intellect and concrete language is known through the senses.

<h3>What are abstract and concrete languages?</h3>

The abstract language uses the words like kind, truth, grace, etc. It is a form of language that indicates the intellectual, but concrete language can be known by the senses.

Thus, the distinction between concrete and abstract language is that concrete language is understood via the senses, whereas abstract language is understood through the mind.
