Option D is correct. The loop should look like this:

for (int i = 0; i < 10; i += 2)
{
     System.out.print(i + " ");
}

Question 1:
Julli [10]

Answer:

Following are the code to the given question:

#include<iostream>//header file

#include<math.h>//header file

using namespace std;

int main()//main method

{

   long long x, x1, y, y1;//defining long variable

   int count=0,i,j;//defining integer variable

   cout<<"Enter a range for x coordinates: "<<endl;//print message        

   cin>>x>>x1;//input x and x1 value                          

   cout<<"Enter a range for y coordinates: "<<endl;//print message

   cin>>y>>y1; //input y and y1 value  

   for(i = x; i <= -x1; i++)//use nested loop that tests each coordinates                                        

   {

       for(j = y; j <= y1; j++)//use nested loop that tests each coordinates

       {

           if(((2*pow(i,2)) + abs(2*i*j) + pow(j,2)) == 10000)//use if that checks condition as per the given question

           {

               cout<<"There is a planet at "<<i<<", "<<j<<endl;//  print coordinates

               count++;//incrementing count variable value                                                    

           }

       }

   }

   cout<<"Total number of planets detected are: "<<count<<endl;//print count value

   return 0;

}

Explanation:

In this code, inside the main method long "x, x1, y, and y1" and integer "count, i, and j" type variable is declared that uses a long variable to input value from the user-end.

In the next step, two nested loops have defined that test each coordinate and define if block that checks condition as per the given question and use i, j, and count variable to print value with the message.

You have to write a program that will read a number followed by a series of bit operations from a file and perform the given ope
tatuchka [14]

The program what will read a number followed by a series of bit operations from file and perform the given operations sequentially on the number is given below.

<h3>What is an operation in computer science?</h3>

An operation, in mathematics and computer programming, is an action that is carried out to accomplish a given task.

There are five basic types of computer operations:

  • Inputting,
  • processing,
  • outputting,
  • storing, and
  • controlling.

<h3>What is the requested program above?</h3>

#include <stdio.h>

#include <fcntl.h>

int main(int argc, char *argv[])

{

  int number, n, v, temp;

  char line[25], fun[10];

  FILE *f = fopen(argv[1], "r");

 

  fgets(line, 24, f);

  sscanf(line, "%d", &number);   //reading the number

  while( fgets(line, 24, f) )

   {

      sscanf(line, "%s %d %d", fun, &n, &v); //reading the commands

      switch(fun[0])           //checking which command to run

      {

          case 'g':    temp = 1;

                      temp = temp<<n;   //shifting for getting that bit

                      printf("%d\n",(number&temp)&&1);

                      break;

          case 's':   temp = 1;

                      temp = temp<<n;   //shifting for setting that bit

                      if(!v)

                      {

                          temp = ~temp;

                          number = number & temp;

                      }

                      else

                      {

                          number = number | temp;

                      }

                      printf("%d\n",number);

                      break;

          case 'c':   temp = 1;

                      temp = temp<<n;   //shifting for complimenting that bit

                      number = number ^ temp;   //xor to complement that bit

                      printf("%d\n",number);

                      break;

          default:printf("not defined");

      }

  }

  return 0;

}

Execution and Output:

terminal-> $ gcc -o first first.c

terminal-> $ ./first file1.txt

Asymmetric key encryption combined with the information provided by a. certificate authority allows unique identification of the
Nesterboy [21]

Answer:

c. both the user and the provider of encrypted data.

Explanation:

In assymetric key encryption, you will need the public key of the sender to decode the information along with your private key to decode the encrypted information. if you don't have any of the keys, you won't be able to read the information. You must have both in order to read the information sent.
