The INC and Dec instruction do not effect the__________ flag

Answer:

The most popular service supported by every early computer networks:-

Telnet

SMTP(Simple Mail Transfer Protocol)

Reason are as following:-

Telnet:-

When there the number of internet using  people was very less They used to get connected with LAN and Telnet.

It was very useful for bidirectional interactive text oriented communication.  

SMTP:-

SMTP(Simple Mail Transfer Protocol) introduced in 1982 and was one of the most used protocol for e-mails.

It is still used extensively and  It was used for very long time to send and receive email messages for a very long time.

Hence, these are the computer network protocols that are being used as the popular devices.

Answer:

a) Variable-A variable is a symbolic name (or reference to) data. The name of the variable reflects what data the variable includes.It's purpose is to saving a data on particular point,it is a name of the address we want to operate.

Example-a,a1,a23,abc,abh_tr etc.

                It should start with the characters, it may include numbers but not in starting and also the underscore at the starting.

b)Constant-A Constant is a value that we can't change, we stores it like a variable.The significance of constant : it's just a poor style to change the velocity of light, the value of pi, and other things like that. if we assumes some value it may produce an error, so making them constants is a type of defensive programming.

Example- pi=3.14 etc.

c) Assignment Initialization-The process of assigning a specific value to a variable at any point in a program or code because of the program logic requirement is known as an assignment operation.

Initialization-Defines and gives an original value in the same declaration to a stated variable.

Example int x = 7;

In this we can initialize the type of variable like - integer,floating etc.

We can declare the variable value in the same line.So,it helps in removing lines and saves time.  

Answer: The c++ program to calculate area and perimeter for different geometric shapes is given below.

#include <iostream>

using namespace std;

void circle();

void square();

void rectangle();

int main() {  

string shape;

char choice;  

do

{

cout<<"Enter the geometrical shape (circle, square, rectangle)." <<endl;

cin>>shape;  

if(shape == "circle")

       circle();        

   if(shape == "square")

       square();        

   if(shape == "rectangle")

       rectangle();        

   cout<<"Do you wish to continue (y/n)"<<endl;

   cin>>choice;    

   if(choice == 'n')

       cout<<"quitting..."<<endl;        

}while(choice != 'n');

return 0;

}

void circle()

{

   float area, circumference;

   float r, pi=3.14;    

   cout<<"Enter the radius of the circle"<<endl;

   cin>>r;    

   circumference = 2*pi*r;

   area = pi*r*r;    

   cout<<"The circumference is "<<circumference<<" and the area of the circle is "<<area<<endl;    

}

void square()

{

   float area, perimeter;

   float s;    

   cout<<"Enter the side of the square"<<endl;

   cin>>s;    

   perimeter = 4*s;

   area = s*s;    

   cout<<"The perimeter is "<<perimeter<< " and the area of the square is "<<area<<endl;

}

void rectangle()

{

   float area, perimeter;

   float b, h;    

   cout<<"Enter the breadth of the rectangle"<<endl;

   cin>>b;    

   cout<<"Enter the height of the rectangle"<<endl;

   cin>>h;    

   perimeter = 2*(b+h);

   area = b*h;    

   cout<<"The perimeter is "<<perimeter<< " and the area of the rectangle is "<<area<<endl;

}

OUTPUT

Enter the geometrical shape (circle, square, rectangle).

circle

Enter the radius of the circle

3.56

The circumference is 22.3568 and the area of the circle is 39.7951

Do you wish to continue (y/n)

n

quitting...

Explanation:

The program performs for circle, square and rectangle.

A method is defined for every shape. Their respective method contains the logic for user input, computation and output.

Every method consists of the variables needed to store the dimensions entered by the user. All the variables are declared as float to ease the computation as the user can input decimal values also.

No parameters are taken in any of the methods since input is taken in the method itself.

Answer: Backtracking

Explanation:

Backtracking algorithm approaches a solution in a recursive fashion whereby it tries to build answers and modify them in time intervals as we progress through the solution. One such backtracking algorithm is the N Queen problem whereby we place N Queen in a chessboard of size NxN such that no two queens attack each other. So we place a queen and backtrack if there is a possibility that the queen is under attack from other queen. This process continues with time and thereby it tends to extend a partial solution towards the completion.

The do-while loop for the given problem is shown below.  

do  

{  

  // user asked to enter two numbers  

  cout<<"Enter two numbers to be added."<<endl;  

  cin>>num1;  

  cin>>num2;  

  sum = num1 + num2;  

  // sum of the numbers is displayed  

  cout<<"Sum of the two numbers is "<<sum<<endl;  

  // user asked whether to perform the operation again  

  cout<<"Do you wish to continue (y/n) ?"<<endl;  

   cin>>choice;  

}while(choice != 'n');  

The variables to hold the two numbers and their sum are declared as float so that the program should work well for both integers and floating numbers.

float num1, num2, sum;

The char variable is taken since it holds only a single-character input from the user, 'y' or 'n'.

char choice;

The whole program is given below.

#include <iostream>

using namespace std;

int main() {

float num1, num2, sum;

char choice;  

do  

{  

  // user asked to enter two numbers  

  cout<<"Enter two numbers to be added."<<endl;  

  cin>>num1;  

  cin>>num2;  

  sum = num1 + num2;  

  // sum of the numbers is displayed  

  cout<<"Sum of the two numbers is "<<sum<<endl;  

  // user asked whether to perform the operation again  

  cout<<"Do you wish to continue (y/n) ?"<<endl;  

  cin>>choice;  

}while(choice != 'n');

cout<<"Quitting..."<<endl;

}

Answer:

non abstract class,abstract

Explanation:

In java a sub class of a concrete class or non abstract class can override a method of its upper class  and declare it abstract . This is because it does not happen very often, but it is useful when the implementation of  the method in the upper class is not valid in the  subclass .

Answer:

You may not use the break statement in a nested loop - False

Answer: Last mile is specific phrase that is referred to the customer  in a technological field. VoIP(Voice over internet protocol) processes used to connect the customer through the voice communication with the help of internet protocol.

Explanation:

Voice over internet protocol is the protocol which uses voice communication to communicate by the help of internet as transmission medium .The terms last mile can be termed as 'last" -final layer and  "mile"- length or distance of the total  voice communication .

Last mile of the internet field in VoIP is the reaching of service to customer or the end user which is the last layer . The quality of service cannot be assured for the last mile and the speed , bandwidth etc factors also get effected in the communication. Therefore the last mile in the VoIP basically establishes the connection of the first mile to last mile that is the voice communication from service sender to the user .

Answer:

A? "A means of proving a person identity"

Explanation:

Answer:

int i,t = 0;

   i=0;  //initialize

   while(i<22){

       t = t + i;

           cout << t;

           i += 3;   //increment

   }

   cout << endl;

Explanation:

Loops are used to execute the part of the code again and again until the condition is not true.

In the programming, there are three loop

1. for loop

2. while loop

3. do-while loop

The syntax of for loop:

for(initialize; condition; increment/decrement){

   statement;

}

The syntax of while loop:

initialize;

while(condition){

   increment/decrement;

}

In the while, we change the location of initializing which comes before the start of while loop, then condition and inside the loop increment/decrement.

Answer:

450 =(702)₈

1101100000110=(15406)₈

Refer to the images for the Truth tables for the AND , OR , NAND gates.

The output of OR gate is High when either of the inputs is 1.It is 0 only when both the outputs are 0.

The output of AND gate is 1 only when both the inputs are 1.If either of the input is 0 output is 0.

The NAND gate is Not AND gate So we have to just reverse the output of AND Gate.Replace 0's to 1's and vice-versa.

Answer: C# , Java

Explanation:

In C# we have an array of array but it is not fixed as it can have different dimensions. Its elements are interface type and are initialized to null.

In java the elements of an array can be any type of object we want such as it can be a rectangle.

In java we can use

String[ ][ ] arrays = { array1, array2, array3, };

Here the string array consist of arrays 1,2,3.

Answer:

A FIELD is recognized as the smallest unit of application data by system software.

Explanation:

Field is recognized as the smallest unit of application data by any system software. The data in relational data base management system ( RDBMS ) is stored as rows also called as database records or simply records. Each record is a row in database and each record contains fields. Columns in data base are nothing but the fields of all the records. They types of fields are fixed length and variable length.

Answer:

Following is the c++ code:-

#include <bits/stdc++.h>

using namespace std;

int main() {

   float a,b,c;//declaring three float variables..

   cout<<"enter values"<<endl;

   cin>>a>>b>>c;//taking input..

   float mi=min(a,b);//finding minimum in a and b..

   mi=min(mi,c);// finding minimum from mi and c.

   cout<<mi<<endl;//printing the answer.

return 0;

}

Explanation:

I have taken three float variables to hold the values.

then I am finding the minimum in a and b and storing it in mi.

Then finding minimum from mi and c so we will get our final minimum number.

Answer:

#include<iostream>

using namespace std;

int main () {

   int n;

   int odd=0,even=0;

  cout<<"Enter the number of element store in the array: ";

  cin>>n;

  int arr[n];

  for(int i=0;i<n;i++){

     cin>>arr[i];

  }

  for(int i=0;i<n;i++){

       if(arr[i]%2==1){

           odd++;

       }else{

           even++;

       }

  }

  cout<<"The number of odd values is: "<<odd<<endl;

  cout<<"The number of even values is: "<<even<<endl;

}

Explanation:

Include the library iostream for input/output.

Create the main function and declare the variables.

Then, print the message on the screen and store the value enter by the user for the size of the array. After that, take a for loop and store the values in the array enter by the user.

then, take a for loop for traversing to the array and check the condition for odd and even by using if-else statement.

for odd: If odd values divided by 2 it gives 1 remainder.

for even: If even values divided by 2 it gives zero remainder.

if condition true, then update the counter.

finally, print the result.

Answer:

All of the given options

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Communication is an insanely important and useful, but there are a lot of misconceptions about communication. Based on the answers given in the question, the correct answer would be "All of the Given Options"

Communication can solve many problems but the statement that it can solve all problems is not completely accurate. Whether communication can solve a specific problem depends varies from person to person.

Communication can physically break down since not everyone speaks the same language not everyone can understand each other. Also another physical way is that certain dialogue choices can lead to physical confrontation.

Lastly, the meaning of a word can mean different things to different people. For example, "Happiness" every single person has a unique definition of happiness while others simply say it doesn't exist.

Answer:

 #include <iostream>

using namespace std;

int main()

{

  float arr[10];

  float sum=0.0;

  for(int i=0;i<10;i++){

      cout<<"enter the 10 student record (0-100): ";

      cin>>arr[i];

  }

  float min=arr[0];

  float max=arr[0];

  for(int i=0;i<10;i++){

      if(arr[i]<min){

          min=arr[i];

      }

      if(arr[i]>max){

          max=arr[i];

      }

      sum = sum+arr[i];

  }

  float avg = sum/10;

  cout<<"Smallest score: "<<min<<endl;

  cout<<"Largest score: "<<max<<endl;

  cout<<"Average score: "<<avg<<endl;

  return 0;

}

Explanation:

Create the main function in the c++ programming and declare the variables.

Then, use the for loop to enter the scores 10 times in the array.

another for loop is used to traversing the array and check for smallest and largest and also calculate the sum of all element in the array.

for check smallest, define the temporary variable min with first element of array.

then, if statement check each element with the min and update the min if condition true.

similarly for largest.

after that, take the average by dividing the sum with total number of element in array.

finally print the output.

True,After inserting (or deleting) a node from an AVL tree, the resulting binary tree does not have to be an AVL tree.

After inserting or deleting a node from an AVL tree, the resulting binary tree does not necessarily have to be an AVL tree. Here's a detailed explanation:

An AVL tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one. When performing operations such as insertion or deletion in an AVL tree, it is crucial to maintain this balancing property to ensure that the tree remains an AVL tree.

However, during the process of insertion or deletion, the balance factor of nodes may become violated, causing the tree to lose its balance. This imbalance can occur due to various factors such as rotations, double rotations, or node restructuring.

In some cases, after inserting or deleting a node, the resulting binary tree may still satisfy the AVL tree property without requiring any additional adjustments. In these cases, the tree remains an AVL tree.

However, there are scenarios where the resulting tree violates the AVL property and becomes unbalanced. In such cases, it is necessary to perform rebalancing operations to restore the AVL property. These operations typically involve rotations or restructuring of nodes to ensure that the heights of the subtrees remain balanced.

Therefore, it is true that after inserting or deleting a node from an AVL tree, the resulting binary tree does not have to be an AVL tree. Maintaining the AVL property may require additional adjustments to restore balance, making it possible for the resulting tree to deviate from the AVL tree structure initially.

Answer:

#include <bits/stdc++.h>

using namespace std;

void funct(){

   string name;

   cout<<"enter the string: ";

   cin>>name;

    reverse(name.begin(), name.end());

    cout<<"The string is : "<<name<<endl;

}

int main()

{

   funct();

  return 0;

}

Explanation:

create the function funct() with return type void and declare the variable type string and print a message for asking to used enter the string.  

The string enter by user is store in the variable using cin instruction.

after that, we use a inbuilt function reverse() which takes two argument.

firs argument tell the starting point and second index tell the ending point. then, the reverse function reverse the string.

name.begin() it is a function which return the pointer of first character of string.

name.end()  it is a function which return the pointer of last character of the string.

finally, print the reverse string.

for calling the function, we have to create the main function and then call the function.

Answer:

Light sources of fiber optics are used to inject light into a fiber optic cable. There are two varieties of light sources: laser diodes and light emitting diodes (LEDs) . They’re further differentiated by the wavelength and the type of cable.

LEDs are economical, slow in speed, easy to handle, multi mode-only, and have a wide output pattern.

Laser diodes are of expensive and faster than LED's, allow single-mode or multi mode both , and have a narrow output pattern.

The correct answer is letter "C": Simulation.

Explanation:

A computer simulation is an algorithm, computer software or a network of servers that have the goal of creating a simulation of an abstract model of a given system. The model is made up of equations that replicate the functional relationships that the real system could have.

Answer:

 back

Explanation:

queue is the data structure which perform operation in particular order.  the order is first in first out (FIFO).

it means the element which comes first, remove first.

front: it is used to fetch the first element or oldest element in the queue.

back:  it is used to fetch the last element or newest element in the queue.  

pop: it is used to remove the first element or oldest element in the queue.

push: it is used to insert the element at the back in the queue.

Therefore, the back is the correct option.

Final answer:

The operation that returns the last element in a queue without removing it is known as the 'back' operation.

Explanation:

The front operation on a queue returns the last element in the queue but does not remove the element from the queue.

The operation on a queue that returns the last element in the queue, but does not remove the element, is known as the back operation. Unlike the pop operation, which removes the element from the queue, the back operation simply allows us to see what the last element is without altering the queue's content. This is particularly useful in scenarios where you need to make a decision based on the last element without actually consuming it.
