Answer:

192.168.228.0 255.255.255.224

Explanation:

192.168.228.0 255.255.255.128

subnet mask: defines the host and the network part of a ip

CIDR notation : is the shortened form for subnet mask that uses the number of host bits for defining the host and the network part of a ip

For example: 192.168.228.0 255.255.255.128 has CIDR equivalent of 192.168.228.0\25

To have atleast 20 hosts

20 ≤ (2^x) -2

x ≈5

with 5 host bits, we have 2^5-2 = 30 hosts per subnet

and 2^3 = 8 subnets

To get the subnet mask, we have 3 network bits

1110000 to base 10 = 2^7 + 2^6 +2^5= 224

192.168.228.0 255.255.255.224

Write a program that prompts the user for the lengths of the two legs of a right triangle, and which reports the length of the h
timurjin [86]

Answer: The following code is in c++

#include <iostream>

#include<math.h>

using namespace std;

int main()

{

   float a,b,c;

   cout<<"Enter height and base of triangle\n";

   cin>>a>>b;  //reading two sides from user

   c=sqrt(pow(a,2)+pow(b,2));  //calculating hypotenuse

   cout<<"Length of hypotenuse is "<<c;  //printing third side of triangle

   return 0;

}

OUTPUT :

Enter height and base of triangle                                                                                            

3                                                                                                                              

4                                                                                                                              

Length of hypotenuse is 5  

Explanation:

In the above code, three variables a, b and c of int type are declared. After that, it is asked from user to enter the value of a and b. The user puts the value and then c is calculated with the help of Pythagoras theorem formulae which squares the values of two sides and then adds them to calculate hypotenuse of a right angled triangle and finally c is printed to console.

Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements and
ASHA 777 [7]

The indices of the internal array elements that hold the remaining elements is c) 2 to 4

<h3>Calculations and Parameters:</h3>

For us to create a capacity of 10 for the queue, we would enqueue:

We would create a queue of capacity 10:

<h3>Queue q(10);</h3>

We add elements/enqueue 5 elements to the queue :

  • q.queueEnqueue(10);
  • q.queueEnqueue(5);
  • q.queueEnqueue(8);
  • q.queueEnqueue(9);
  • q.queueEnqueue(2);

Printing this would give:

q. queueDisplay()

10, 5, 8, 9, 2

Next, we would remove elements/dequeue 2 elements from the queue :

q. queuedequeue();

q. queuedequeue();

Printing it would be:

q. queueDisplay()

8 ,9, 2

Observing this, the deletion/dequeue starts from the front/first index.

The remaining indices of the internal array elements are: 2, 3, 4 or 2 to 4
