Answer:
Incremental technique is the way in which software is built and delivered in pieces. The concept is to keep the client and developer on same page and the client is known as a non tech person, so he should be given software in piece by piece to avoid any confusion and sudden change.
Agile method is the best example of this technique in which steps are defined on contract basis and the software is delivered and build by pieces to keep client and developer on same page.
Software delivered in pieces is associated with the Agile Method and iterative development, allowing for a product to be enhanced over time with new features and updates.
Software built and delivered in pieces is commonly known as iterative development or incremental delivery, which is a core principle of the Agile Method. This approach contrasts with traditional software delivery, where a complete and final version is provided to the user. With Agile, developers can release a basic version of an application, such as a game or app, and then continuously add features and updates over time. The idea is to deliver a product step by step, enhancing its functionalities based on user feedback and changing requirements.
Iterative development is possible through the Agile Method, which emphasizes the quick delivery of small, workable pieces of software rather than waiting to deliver a complete and potentially outdated product. New features can be added, and changes can be made dynamically, which is highly beneficial in an environment where customer needs are constantly evolving. This method embraces flexibility and focuses on rapid delivery of high-quality, usable chunks of functionality.

Who needs to approve a change before it is initiated? (Select TWO.)
-Change board
-Client or end user
-CEO
-Personnel manager
-Project manager
Final answer:
Changes must typically be approved by the Change board and the Project manager before being initiated. Input from stakeholders such as clients or end users is also valuable for buy-in, but formal approval is usually from specific governing entities.
Explanation:
The individuals or groups that need to approve a change before it is initiated typically include the Change board and the Project manager. The Change board, also known as a change advisory board (CAB), is responsible for assessing and approving significant changes to ensure they align with the project's goals and the organization's strategic direction. The Project manager is accountable for the successful execution of the project and must ensure that any changes fit within the project's scope, budget, and timeline.
The involvement of other stakeholders such as the Client or end user may be required depending on the nature of the project and the organizational structure. The Client or end user is crucial for providing buy-in, as their feedback validates the relevance and potential impact of the change on the final deliverables. Input from stakeholders at all levels is essential, yet the formal approval typically rests with specific entities tasked with governance.
Each organization has different protocols, and depending on the size and type of organization, other roles such as the CEO or Personnel manager can be involved; however, typically their approval is not required for initiating changes unless stipulated by the organizational policies.
Invalid length parameter passed to the LEFT or SUBSTRING function (below)".
How can this be handled?
LEFT(U.FULLNAME,charindex(',', U.FULLNAME)- 1) AA, CHARINDEX(LEFT(U.FULLNAME,charindex(',', U.FULLNAME)- 1), P.Project_Name) CCOUNT
This error occurs when the number of arguments sent to the function are not equal ( greater or less ) to the parameters of the function.
For example:
// if the function is
void a_function(int a, int b){
// does some computations
}
// Now when i will call it as
a_function(3);
// Same error as you are getting will occur because the function expects 2 //argements and i am passing one.
Same will happen if i will call it as:
a_function (1,2,3);
Here i am passing one extra argument.
So, i will suggest to count the left function parameters and the arguments you are passing here in this function and you will find the mistake.

Which sentence(s) below are true?a. IP stands for Internet Protocol.b. In most home networks IP addresses are assigned by the Internet Service Provider. c. If two laptops are connected to the same home network and surfing the web simultaneously, each laptop must have its own IP address. d. If two laptops are connected to the same home network and surfing the web simultaneously, they share the same IP address.
Option A is true because IP is short form of Internet protocol.
Option B is true because when every device is connected to the servers by using internet, Internet Service providers assign them unique IP address to define their identity on internet and monitor their activities.
Option C is false because no matter how many laptops or devices are connected to a same router through a network Internet Service Providers assign them a same IP address.
Option D is true because every laptop or device connected to the internet by a network is given the same public IP or external IP.
IP does stand for Internet Protocol, and in a home network, IP addresses are assigned by the ISP. Each device on a local network has its own IP address, but all share the same external IP address when accessing the Internet.
IP stands for Internet Protocol, which is a set of rules governing the format of data sent over the Internet or other networks. Let's address the student's questions one by one:
a. True. IP does indeed stand for Internet Protocol.b. True. In most home networks, IP addresses are usually assigned dynamically by the Internet Service Provider (ISP).c. True. If two laptops are connected to the same home network and are surfing the web simultaneously, each laptop must have its own IP address internally, within the local network, often provided by the router.d. False. While each device on the home network has its own internal IP address, all devices share the same external IP address assigned by the ISP when connecting to sites and services on the Internet.Each device on a network communicates with other parts of the network (and the Internet) using an IP address, which serves as a unique identifier. In the context of a home network, the router typically assigns an internal IP address to each device, while the ISP assigns one external IP address to the entire network.
max is a method that accepts two int arguments and returns the value of the larger one. Four int variables, population1, population2, population3 and population4 have already been declared and initialized. Write an expression (not a statement !) whose value is the largest of population1, population2, population3 and population4 by calling max. Assume that max is defined in the same class that calls it.
Answer:
Hello, I imagine that you use Java as the programming language since you refer to classes, so I will make a small code that simulates a Java program with the descriptions you need.
public class Example {
public int Max(int population1, int population2, int population3, int population4) {
int max = 0;
if(population1 > population2 && population1 > population3 && population1 && population4){
max = population1;
}
else if(population2 > population1 && population2 > population3 && population2 && population4){
max = population2;
}
else if(population3 > population2 && population3 > population1 && population3 && population4){
max = population3;
}
else {
max = population4;
}
return max;
}
public static void main(String[] populations) {
Example myObject = new Example();
int population1 = 1;
int population2 = 2;
int population3 = 3;
int population4 = 4;
int max = myObject.Max(population1,population2,population3,population4);
System.out.println(max); // 4
}
}
Final answer:
The expression to find the largest value among four integer variables using the max method would be max(max(max(population1, population2), population3), population4).
Explanation:
To find the largest value of population1, population2, population3, and population4 by calling the max method, you would use a nested call to the max method. You would call the max method with two of the populations, and then use the result along with the next population in another call to max, and repeat this until all populations have been considered. This results in an expression (not a statement) that looks like this:
max(max(max(population1, population2), population3), population4)
This expression uses the max method to first compare population1 and population2, then compare the result of that with population3, and finally compare the result of the previous comparisons with population4 to find the largest of the four values.
Class members are accessed via the ____(1)_____ operator in conjunction with the name of an object of the class, or via the ___(2)_____ operator in conjunction with a pointer to an object of the class.
Answer:
1.ClassName and . operator
2. ClassName and [] operator
Explanation:
There are two ways to get the members of a class first one is by using dot(.) operator.
Example : with assumption that person is a class object and age is the member in it we can use it as:
person.age
Second way is to use [] operator with member as a string in it which is used by the compiler as key to get its value.
Example : person["age"]
Class members are accessed via the dot (.) operator with an object name, or the arrow (->) operator with a pointer. This is part of object-oriented programming which involves classes and objects that encapsulate data and methods.
Explanation:Class members are accessed via the dot (.) operator in conjunction with the name of an object of the class, or via the arrow (->) operator in conjunction with a pointer to an object of the class.
In the context of object-oriented programming, when we work with classes and objects, we deal with functions called methods and variables referred to as instance variables. Methods are used to define the behavior of objects while instance variables store data for each object.
An object, quite simply, can be seen as a segment of memory that includes instance variables representing data, and methods to work with that data. A class serves as the blueprint which outlines the methods by which objects can interact with their data.
Write the definition of a function named maxmin that is passed four int arguments. The function returns nothing but stores the larger of the first two arguments in the third argument it receives and the the smaller of the first two arguments in its fourth argument. So, if you invoke maxmin(3,7,x,y), upon return x will have the value 7 and y will have the value 3.
Answer:
To get the values in x and y, we should use the pass -by -reference method. Where a reference to the actual variable is created in the called function. When we update the value inside the called function, it reflects in the calling function.
C++ code:
#include<iostream>
using namespace std;
void maxmin(int p, int q, int &r, int &s);
int main()
{
int k,l,x,y;
cout<<"Enter two integers for k and l: ";
cin>>k>>l;
maxmin(k, l, x, y);
cout<<"The maximum of two numbers is: "<<x<<endl;
cout<<"The minimum of two numbers is: "<<y<<endl;
}
void maxmin(int p, int q, int &r, int &s)
{ //r and s holding the address of x and y respectively.
if(p>q)
{
r=p;
s=q;
}
else
{
r=q;
s=p;
}

What is a digital certificate? Select one: a. It is a means of establishing the validity of an offer from a person, entity, web site, or email. b. It is a centralized directory wherein registered keys are created and stored. c. It is a means of establishing your credentials electronically when doing business or other transactions on the Web. d. It is an entity that generates electronic credentials and distributes them upon proving their identity sufficiently.
Option D is the answer because Digital Certificate is an entity that generates electronic and distributes them upon proving their identity sufficiently. In early days there was issues with people using the certificates that were not even issued by the organizations. Today it's a cryptographic technique which uses digital signatures and gives users a digital certificate that can be authenticated anytime online by any organization and is unique for every user having it.
Option A cannot be the answer because it has nothing to do with the identity of person but rather it is for specific fields.
Option B is not answer because it has no key and score matter to do with it.
Option C Web transactions has nothing to do with the certificates.
Given that two int variables, total and amount, have been declared, write a loop that reads integers into amount and adds all the non-negative values into total. The loop terminates when a value less than 0 is read into amount. Don't forget to initialize total to 0
Answer:
total=0;
do{
cin >> amount;
if (amount>0)
total += amount;
}
while (amount >=0);
Explanation:
A loop that reads integers into amount and adds all the non-negative values into total is shown below.
Now, Here's a code snippet that should do what you're asking for:
int total = 0;
int amount = 0;
while (amount >= 0) {
// read integer input from user
scanf("%d", &amount);
// add input to total if non-negative
if (amount >= 0) {
total += amount;
}
}
Here's how this code works:
First, we initialize total to 0 and amount to 0.
Then we enter a while loop that will continue as long as amount is non-negative.
Within the loop, we read an integer input from the user using the scanf function.
We then check if the input is non-negative using an if statement.
If the input is non-negative, we add it to the total variable.
If the input is negative, we skip the if statement and proceed to the end of the loop, at which point the loop terminates.
Finally, once the loop terminates, we have added up all the non-negative input values, and total contains their sum.

Explanation:
what examples of the influence of the media on current events. Are there, or should there be, limits on the power of the media? Should there be extra restrictions on the events and individuals that the media is allowed to report?
I believe that there should be limits to the use of social media, regarding using it for absurd pointless things as taking constant selfies of oneself, and who you message. I do think that taking pictures is okay, as long as it regards taking pictures of sceneries and of people we treasure, but taking endless pictures of oneself over and over again is pointless. We should also limit the use of social media because people become easily addicted, especially for people's in their teens, spending hours either talking to people they dont know or talking to people they do know, which either way, they are spending too much time doing; they aren't getting any exercise done and are increasing there chance of contracting a headache and becoming blind/having lower vision. I believe that social media should only be used for contacting people when we need to, not just to talk each other's ears of all day, and sharing important information to people that need to be aware of things. So in conclusion, yes, there should be restrictions on the events and individuals that the media is allowed to report because a majority of people will spend 50% of there time to useless things, when they aren't living there life to their fullest potential.

How do i add the sum of a column in excel?
Excel has a built in sum function to calculate the sum of elements. The syntax of this function is:
=sum(argument)
This formula is written in the destination cell where we need our sum to show up.
The argument is the cells , columns or range of cells and columns for which we need to find the sum. If we need to find the sum of elements in a column, the formula will be like:
= sum(A:A)
This formula will find the sum of all elements that are present in the column A. The argument in the above formula is A:A which represents that entire column A is selected.
This formula can be modified according to the needs. For example, if we need to find the sum of two columns A and B, the formula will be:
=sum(A:B)
This formula calculates the sum of all elements in columns A and B.
