Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter. Ex: sortArray = {10,

sergey [27]

Answer:

Here is the SwapArrayEnds()

//function with two parameters; the array and array size

void SwapArrayEnds(int sortArray[],int SORT_ARR_SIZE){

int temp; //temporary variable to hold the first element of sortArray

if(SORT_ARR_SIZE > 1){ //if sortArray size is greater than 1

temp = sortArray[0]; // set value of temp to the first element of sortArrray

sortArray[0] = sortArray[SORT_ARR_SIZE-1]; // set the value of first element of sortArray to the last element of sortArray

sortArray[SORT_ARR_SIZE-1] = temp; } } // set last element value to temp

Explanation:

Lets understand the working of the above function with the help of an example. Suppose the sortArray has the following elements: {10,20,30,40}. So the size of this array is 4.

if(SORT_ARR_SIZE > 1) has an if statement which checks if the array size is greater than 1. This condition evaluates to true as 4 > 1. So the body of if condition executes.

Next the statement temp = sortArray[0]; sets the value of temp variable to the value of first element of sortArray. As sortArray[0] means the element at 0-th index position of the sortArray. So using the above example the first element of the array is 10. So temp = 10.

Next the statement sortArray[0] = sortArray[SORT_ARR_SIZE-1]; sets the last element of the sortArray to the position of first element of the sortArray.

SORT_ARR_SIZE-1 is the position of last element of the array. As the size of sortArray is 4, so 4-1 = 3 which points to the last element. Now this element is moved to the first position of the array. This means that the value of first element of array becomes 40 as the element at 3-th index of the sortArray is 40.

Next the statement sortArray[SORT_ARR_SIZE-1] = temp moves the value in temp variable to the last position of the sortArray. As we know that the value of temp= 10. So this element 10 of the sortArray is positioned at SORT_ARR_SIZE-1 position of sortArray which is 4-1 = 3-th index of sortArray. This simply means that 10 is moved to the last position of sortArray.

So now the final sortArray becomes: 40,20,30,10 as the first and last element of the array are swapped using above function SwapArrayEnds().

The program along with the output is attached in screenshot.

Answer:

C. ATA Secure Erase

D. Smash the USB drive

Explanation:

Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.

Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.

ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.

Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.

In cell h15 enter a vlookup function to determine the 2018 percentage of total attendance for the city listed in cell h14. Use t

Amanda [17]

Answer:

=vlookup(h14, a5:h11,8,false)

Explanation:

Here, h15 is the cell in which we need the output and the value to be matched in rows to find the exact row is h14, and the range is expressed as a5:h11. Now to find the column number, we need to figure out the first and the concerned column. So, the concerned column is in which the total attendance is being listed and it is h(h14), and the first column is a. So, the column number is a=1 h=8, =8. And since we need the exact match, the value of the fourth argument is false. And thus, we have the above formula. Remember. vlookup formula is:

=vlookup(cell where the result is to be placed, range, column number in the same row as h14, exact match or approximate match). For exact match it's false, and for the approximate match, it's true.
