What are the advantages and disadvantages of UTF-8 compared to ASCII?

Computers and Technology
1 answer:
Romashka [77]3 years ago
6 0

Answer:

UTF-8 and ASCII both are the character encoding.

In a system,every character has some binary representation,these are the method to encode them.Earlier only ASCII was there, for every character it uses 8 bits to represent.In ASCII only 8 bytes were there i.e 2^8 that is 256.We can't represent number beyond than 127 so it generate a need for other encoding to get into,these drawbacks lead to Unicode,UTF-8.

As ASCII codes only uses a single byte,UTF-8 uses upto 6 bytes to represent the characters.So we can save characters which are as long as 2^48 characters. We can read this encoding easily by the help of shift operators and it is also independent of byte order.

As messages on internet were transferred over 7 bit ASCII messages,so many mail servers removed this encoding.

1.What is the output of the following program? [10 Marks]namespace ConsoleApp1{class Program{static void Main(string[] args){int
Nataliya [291]

The program outputs the following rectangular array:

0 0 0 0

0 1  2 3

0 2 4 6

0 3 6 9

0 4 8 12

This is the correctly formatted C# program:

namespace ConsoleApp1{

   class Program

   {

       static void Main(string[] args)

       {

           int i, j;    // <em>declare index variables used to iterate over the array A</em>

           int [,] A = new int[5,5];   // <em>create a 5 by 5 array</em>

           

           /*<em> Iterate over the array with the index variables i and j</em>

<em>                and initialize each location A[i, j] with the product </em>

<em>                of i and j.</em> */  

           for (i = 0; i < 5; ++i)

           {

               for (j = 0; j < 4; ++j)

               {

                   A[i, j] = i*j;

               }

           }

           

           /* <em>Iterate over the array again. This time, swap locations </em>

<em>                A[i, j] with A[j, i]</em> */

           for (i = 0; i < 5; ++i)

           {

               for (j = 0; j < 4; ++j)

               {

                   if (i < 5)

                   {

                       A[j, i] = A[i, j];

                   }

                   else

                       break;

                   

                   // <em>display the current location A[i, j]</em>

                   Console.Write(A[i, j] + " ");

                   

               }

               /* <em>print a newline to prepare for the next line of printing</em>

                   <em>which corresponds to the next column i</em> */

               Console.WriteLine();

                // <em>pause and wait for user keypress before continuing</em>

               Console.ReadLine();

               

               }

           }

       }

   }

When executed, this program simply prints a rectangular array like so;

0 0 0 0

0 1  2 3

0 2 4 6

0 3 6 9

0 4 8 12

3.14 LAB: Simple statistics for Python
Ad libitum [116K]

Answer:

Following are the correct python code to this question:

n1 = float(input('Input first number: '))#input first number  

n2 = float(input('Input second number: '))#input second number  

n3 = float(input('Input third number: '))#input third number  

n4 = float(input('Input fourth number: '))#input fourth number  

average = (n1+n2+n3+n4)/4 #calculate input number average

product = n1*n2*n3*n4 # calculate input number product

print('product: {:.0f}  average: {:.0f}'.format(round(product),round(average))) #print product and average using round function

print('product: {:.3f}  average: {:.3f}'.format(product,average)) #print product and average value

Output:

Please find the attachment.

Explanation:

The description of the above python code can be defined as follows:

  • In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
  • In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
  • In the last line, the print method is used, which prints its variable value by using a round and format method.

2. Consider the two-dimensional array A: int A[][] = new int[100][100]; where A[0][0] is at location 200 in a paged memory syste
bogdanovich [222]

Answer:

Check the explanation

Explanation:

An integer (int) is of two different bytes and each page has 200 bytes in length. What this means is that each row of array A (100 int) will fits perfectly in a page.

(a) For the initial or first array-initialization loop, one column is processed at a time, so a page fault will be generated at every inner loop iteration, with a total of 100*100=10,000 page faults.

(b)  And when it comes to the second array-initialization loop, one row is processed at a time, and a page fault is generated at every outer loop iteration, with a total of 100 page faults.

Hence second array-initialization loop, has better spatial locality.
