Below are suggestions Ryan and Michael should be aware or when travelling away from home with portable personal digital devices.


Portability: This includes the size and weight. Always keep portable equipment like phones and laptops in your possession every time.

Power adapters or chargers: At one point, you will need to recharge your phone or laptop. Bring your charger, plug adapter or a voltage converter if traveling overseas.

Mobile networks or Data roaming charges: When traveling overseas, it is worth noting that your data plan will probably be very expensive. Be sure to turn off 3G and push services and disable notifications.

Connectivity and availability of the internet: Doing a research on the connectivity well before your departure date is vital. Ensure to find out whether free wireless is offered at your hotel. If you must connect to any public hot-spots, be careful not to enter personal information like passwords and credit cards numbers.

Personal security and the security of the device: If you are set to travel to a dangerous part of the world, leave your expensive electronics behind and find alternative ways of how you can stay in touch with family and friends

What is the value of the totalsString variable after the following code is executed? var totals = [141.95, 212.95, 411, 10.95];
Alex Ar [27]
<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|
