Find the maximum value and minimum value in milesTracker. Assign the maximum value to maxMiles, and the minimum value to minMile

s. Sample output for the given program:Min miles: -10Max miles: 40#include using namespace std;int main( ) { const int NUM_ROWS = 2; const int NUM_COLS = 2; int milesTracker[NUM_ROWS][NUM_COLS]; int i = 0; int j = 0; int maxMiles = -99; // Assign with first element in milesTracker before loop int minMiles = -99; // Assign with first element in milesTracker before loop milesTracker[0][0] = -10; milesTracker[0][1] = 20; milesTracker[1][0] = 30; milesTracker[1][1] = 40; /* Your solution goes here */ cout << "Min miles: " << minMiles << endl; cout << "Max miles: " << maxMiles << endl;}

Answer:

Following are th program in the C++ Programming Language.

#include <iostream>//set Header files

using namespace std;//set namespace

//define main function

int main()

{

//set integer constants variable

const int NUM_ROWS = 2;

//set integer constants variable

const int NUM_COLS = 2;

//set integer type array

int milesTracker[NUM_ROWS][NUM_COLS];

//set integer type variable and initialize to 0

int i = 0;

//set integer type variable and initialize to 0

int j = 0;

//set integer type variable and initialize to -99

int maxMiles = -99;

//set integer type variable and initialize to -99

int minMiles = -99;

//initialize the value in the two dimensional array

milesTracker[0][0] = -10;

milesTracker[0][1] = 20;

milesTracker[1][0] = 30;

milesTracker[1][1] = 40;

//here is the solution  

maxMiles = milesTracker[0][0];

minMiles = milesTracker[0][0];

/*set for loop to find the minimum miles and maximum miles*/

for (i = 0; i < NUM_ROWS; i++)

{

 for (j = 0; j < NUM_COLS; j++)

 {

 //set if condition for maxMiles is the bigger than

   if (milesTracker[i][j] > maxMiles)

   //initialize milesTracker[i][j] to maxMiles

     maxMiles = milesTracker[i][j];

   //set if condition for minMiles is the smaller than

   if (milesTracker[i][j] < minMiles)

   //initialize milesTracker[i][j] to maxMiles

     minMiles = milesTracker[i][j];

 }

}

//print output

cout << "Min miles: " << minMiles << endl;

//print output

cout << "Max miles: " << maxMiles << endl;

return 0;

}

<u>Output:</u>

Min miles: -10

Max miles: 40

Explanation:

Here, we define the main method and inside it:

  • set two constant integer type variable and initialize to 2
  • set integer type two-dimensional array and pass constant variables in it.
  • Set two integer type variable and initialize to 0 then, again set two integer type variable and initialize to -99.
  • Initialize the values in the two-dimensional array.
  • Set two for loop for the two-dimensional array to find the minimum and maximum miles.
  • Set two if condition to find bigger or smaller miles.

Finally, print the maximum and the minimum miles then, return 0.

Basile [38]

Answer:

The answer is "Using the DoD 5220.22-M method and  Degauss media with a magnet".

Explanation:

The "DoD Standard" is a term used during the data sanitizing industry and refers to DoD 5220.22-M. The simplest ways are being used to help eliminate the previously stored data, by deleting hard disc storage facilities with the same data wherever that used a sequence of all zeros.

The sparging eliminates statistics to entirely delete the gravitational flux from electronic media. Hard drives as well as other data storage devices, for example, computer tapes, retain magnetic data. It could no longer be seen as storage after a disk is degaussed.

At the Data Link Layer of the OSI Model, what type of address is used to identify the receiving host?
Natalka [10]

Answer:

Mac Address

Explanation:

The MAC address or Media Access Control  is a unique identifier that each manufacturer assigns to their devices that can connect to the network.  They consist of 48 bits in hexadecimal form, grouped into 12 pairs of characters and each character is formed by four binary numbers, generally separated by a colon. MAC addresses are used in the data link layer of the OSI model, specifically in the lower Medium Access Control layer. An example of a MAC address could be:

10: 68: c5: 5e: 27: 3f.

2. Research, find and use a better (different from the simple Shift Cipher) encryption technique to encrypt a string of your cho
Kruka [31]

Answer:

There are two better techniques for encryption as compared to shift cipher. One is block cipher. Such techniques use one key for both encryption and decryption. For example Advanced Encryption Standard (AES). This is based on symmetric key encryption.

The other way is to use asymmetric key encryption technique which based on two keys i.e. public and private key for encryption and decryption. For example, Rivest-Shamir-Adleman (RSA).

Explanation:

What is AES?

Advanced Encryption Standard (AES) is a symmetric key block cipher  which uses 128, 192 or 256-bit keys  length to encrypt and decrypt a block of plain text or message. It is stronger and faster than Shift Cipher encryption technique. It can encrypt data blocks of 128 bit using the above mentioned bit key lengths. The greater then key length the greater the security. the number of rounds in AES is variable and depends on the length of the key. The length of these keys determines the number of rounds for example 128 bit keys has 10 rounds, 12 rounds for 192 bit keys and 14 rounds for 256 bit keys. Each rounds involves some processing. This process is explained below:

How AES works?

The data is divided into each of size 128 bits makes a matrix of 4x4 columns of 16 bytes. (bytes because AES takes 128 bit plain text block as 16 bytes)

Substitution: First the data is substituted using a fixed substitution table which is predetermined. This makes a matrix of rows and columns.

Shifting: Each rows of the matrix is shifted to the left and the dropped entries in row are inserted on the right. Shift is carried out as follows −  

Mixing columns: Use a mathematical method/equation to transform the columns where the input of the method is each column of data which is then replaced by this function into a different new matrix of data(bytes). This is basically the first round to transform plain text to cipher text. Now consider these bytes as 128 bits, the first round key is added to these resultant column bits by XOR. A separate portion of the encryption key length is used to perform the transformation on each column. The number of rounds depend on the the key length.

After the first round key comes the second round key and so on and when the last round key is added then this whole process goes back to Substitution phase, then shifting rows phase, then mixing columns and another round key is added after this. For example, if 128 bit key is used this means there will be nine such rounds.

Advantages

AES supports large key sizes which makes it more secure and stronger than shift cipher encryption techniques which can be cracked because of their small key space. If someone wants to decrypt a message and knows it's encrypted by a Shift Cipher technique then the key space of all possible keys is only the size of the alphabet. This is a very small scale.  An attack such brute force attack attempting all 26 keys or even using exhaustive technique will easily crack this. So AES having large key size is more robust against cracking. For example in AES in order to crack an encryption for 128 bit around 2128 attempts are needed. Also for a 256 bit key, 2256 different combinations attempts are needed to ensure the right one is included which makes it harder to crack and makes is more secure.

I have used an internet solver to encrypt a string and i am attaching the result of the encryption. The plain text is: Two One Nine Two

The key is Thats my Kung Fu

and the cipher text in hexadecimal after using AES is:
