Which element would the search element be compared to first, if abinary search were used on the list above?
4
35
44
98
Answer:
35
Explanation:
Binary search is more efficient than linear search,time complexity of binary is 0(logn) where as linear's 0(n).In binary search we search from the middle of the array,whereas in linear we start with index 0 until the last.
4
35
44
98
List contains 4 elements, for finding the middle element we will divide by 2 .
4/2=2 so at the index 2 -35 is present ,we will start checking from 35.
You have the templates of 2 classes, Person and Program. The Person class has 4 attributes, name, age, major and gpa. There is a constructor for the class that is used to make Person objects. There are setter/mutator methods and getter/accessor methods for those attributes. There is also a printInfo() method that prints out information about the person. The Program class has a main method that has 5 Person objects person1 to person5 declared and initialized. The main method within the class also has a Scanner object that is used to take input for a person number and a newGPA. Your task is as follows:
a. Based on the input of personSelect select the appropriate person and change their GPA to the newGPA input and then print out their information. For instance if the user types in 1 then select person 1 and print out their information using the printInfo method. Do it for all possible inputs from 1 to 5.
b. If however the input is not 1 to 5 then inform the user they have to have to type in an appropriate person number
Person.java
public class Person {
String name;
int age;
double gpa;

Scanner scan = new Scanner(System.in);
System.out.println("Type in a person number whose gpa you would like to change > ");
int personSelect = scan.nextInt();
System.out.println("Type in the gpa you would like the person's to be > ");
double newGPA = scan.nextDouble();
/*
* CODE HERE
*/
}
}
Answer:
Hi, I'm going to put the code answer here and you put in the corresponding line to not copy all the code in the answer.
replace the following line or adjust to the following code
/*
* CODE HERE
while(personSelect <= 0 || personSelect > 5) {
System.out.println("Wrong number, try to input the number in range 1 to 5" );
personSelect = scan.nextInt();
}
if(personSelect == 1){
person1.setGpa(newGPA);
printInfo()
}
else if(personSelect == 2){
person2.setGpa(newGPA);
printInfo()
}
else if(personSelect == 3){
person3.setGpa(newGPA);
printInfo()
}
else if(personSelect == 4){
person4.setGpa(newGPA);
printInfo()
}
else {
person5.setGpa(newGPA);
printInfo()
}
*/
Explanation:
According to the description of code, we have to add some lines to resolve the questions.
a):
In base on the input, we have to modify the attribute GPA with the method setGpa depending on the person chosing. We call the person chosen before and also call the method setGpa( ) and pass as parameter the GPA value obtained in tha last input
b)
In this case we have to create a loop for iterate the times that is necesary to get a value of person that is permit in range 1 to 5, and hence that we create and individual if condition to assign the GPA to the person chosen.
I hope it's help you.

If statements- This statement is used to check the condition.
if(condition)
{
statement
}
If the condition is true,then statement will run,else not.
Switch statement-This statement is used for long conditions.It is a substitute for if,else conditions
switch(a)
{
case1: statement 1//if a=1
break;
case2: statement 2 //if a=2
break;
.....
default:statement//if a is not equal to any of the cases.
Multiway if-In this statement ,if elseif and else were there.
if(condition1)
{
statement 1
}
elseif(condition2)
{
statement 2
}
..............
else
{
statement n
}
Nested loops-This statements are used when we use if-else conditions in other if,else conditions.
if(condition 1)
{
if(condition 2)
{
if (condition 3)
{
statement 3
}
else
{
statement 4

rand()-This method is used for generating random number.The expression is
number=rand()%50;
It will generate a random number ranges between 0 to 50.
srand()-This method is used to set the starting value for random number series.
srand (time(NULL));
seed()-It is a method for initializing the same random series,it is passed in srand().
What is the purpose and significanceof the following programming constructs in any programminglanguage
a) Variable
b) Constant
c) Assignment Initialization
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.

Public classes are accessible by all objects, which means that public classes can be ____, or used as a basis for any other class.
a.
copied
b.
used
c.
saved
d.
extended
Answer:
The correct answer is d.extended.
Explanation:
In order to have a superclass in Java, it is indispensable to extend, or inherit from, a class. It means that a subclass is created by an extended class. All the classes in Java only need one superclass from which it inherits some of its fields and methods.
Answer:
d.extended
Explanation:
The answer is d.
You usually has a top public class, for example, animals, with it's own attibutes. Then you can have other classes extending animals, for example, cats. These classes have both the attributes of the parent class, and their own attributes.
So the code goes something like this
public class Animals{
public Animals(){
\\constructor with attributes
}
\\code
}
public class Cats extends Animals{
public Cats(){
\\constructor with the extra attributes.
}
\\code
}
Which of the following statements is FALSE?

c. Nonbottleneck resources have a less than 100% utilization.
d.A bottleneck resource does not always have the longest processing time.
In a java program, package declaration .................... import statements.
A) must precede
B) must succeed
C) may precede or succeed
D) none
Answer: (A)must precede
Explanation:In java, import statements are important part that allows to import the whole package or any specific class in the package.It is used to import the built-in as well as user defined packages into the java source files and because of this your class can also refer to outside class of other packages as well in a direct way.
In a java program, package declaration must precede import statements.
In a Java program, the package declaration, if present, must be the first line in the source file, excluding comments. This is because the package declaration defines the namespace in which the classes are stored, and it is crucial for the Java compiler to know the package before it processes any import statements or class definitions.
Import statements come after the package declaration and before any class or interface definitions. They allow the program to refer to classes that are declared in other packages, making the code more modular and easier to manage. The typical order in a Java source file is:
1. Package declaration
2. Import statements
3. Class or interface definitions
If a source file does not have a package declaration, it is placed in the default package. Proper ordering is essential for the correct compilation and organization of Java programs.
The correct answer is A) must precede.

What is meant by instruction pipelining in RISC processor? Whatare
'/ the problems that may accompany this technology?
Answer:
Explanation:
The instruction pipelining refers to various stages the instruction has to go through for the full execution of the instruction. Each instruction undergoes various stages in the execution, they are Instruction Fetch, Instruction Decode, Address Generator, Data Fetch, Execution and Write Back. Not every instruction may go through all the stages stated above. Pipelining exploits the parallelism in the execution of instructions (executing multiple instructions simultaneously ). Each instruction might be at different stage in the execution of program. It can be a 3-stage pipelining or 5 stage pipelining.
The implementation of Pipelining is a complex procedure.
In branch instructions, the complexity increases with the number of stages of pipeline.

The ____ operation on a queue returns the last element in the queue, but does not remove the element from the queue
A.
front
B.
back
C.
pop
D.
push
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.
Write a program that will prompt the user to input ten student scores to an array. The score value is between 0 –100. The program will display the smallest and greatest of those values. It also displays the average score.
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.

What will the following code print out: int numbers [] = {99, 87, . 66, 55, 101}; for (int i = 1; i < 4; i++) cout << numbers [i] << end1;a) 99 87 66 55 101 b) 87 66 55 101 c) 87 66 55 d) Nothing.
Answer:
87 66 55
Explanation:
Array is used o store the multiple values with same data type.
the array show a decimal value .66, i assume this is enter by mistake because option has no decimal value.
The index of the array is start from zero, it means the first element store in the array at position zero.
In the for loop the variable 'i' start from 1 not zero and it goes to i<4 means i=3.
So, it access the element from 2 to 4 because the index is position of element less than 1.
Therefore, 87 66 55 print.
You are required to write a calculator for Geometric shapes(Circle, Square, and Rectangle). The basic idea is that you willprovide the information regarding a geometric shape and yourprogram will calculate the area, circumference and perimeter.

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.
Write a "while" loop equivalentto the following "for" loop: (2Points)
int i,tt = 0;for (i = 0; i < 12; i += 3){t = t + i;cout << t;}cout << endl;
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.

what is last mile in VOIP
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 .
The ____ algorithm tries to extend a partial solution toward completion
A.
backtracking
B.
recursive
C.
backordering
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.
What are the light sources offiber optics?
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.

What are the asynchronous protocolsin data link layer?
Answer: Asynchronous protocol in data link layer is defined as the protocol which works with single characters or byte and not in the form of blocks of data.
Explanation: Data link layer has the asynchronous protocol which deals with single byte or character at a time rather than working in block order for the data.the data is transferred from one node to another node in individual byte or character and it is observed that the data bytes that are sent is received in the same form .
Convert the following decimal numb er (450)m into octal number system ? Convert the following binary number 1101100000110 into itsoctalequivalent ? Describe the function table of AND, OR, and NAND ?
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.
