What will be the output of the following code snippet? token = False while token : print("Hello")
A) "Hello" will continue to be displayed until the user stops the program.
B) No output because of compilation error.
C) No output after successful compilation.
D) "Hello" will be displayed only once.
Answer:
Hi!
The correct answer is B.
Explanation:
The code snippet doesn't follow the correct form of writing a while loop, so it will crash when compiles.
One correct form to write the code is:
token = false;
while (token){ // Evaluate token, if true prints else terminates the loop. In this case, token is false so, no output and finish the program.
print("Hello");
};

In a class hierarchy A. The more general classes are toward the bottom of the tree and the more specialized are toward the top B. The more general classes are toward the top of the tree and the more specialized are toward the bottom C. The more general classes are toward the left of the tree and the more specialized are toward the right D. The more general classes are toward the right of the tree and the more specialized are toward the left
Answer:
Option B
Explanation:
Option A is rejected because the general behavior of the objects are the reason that the classes concept was introduced and thus the general class should be on the top.
Option B is selected because down the hierarchy the common behavior in classes are reduced and thus they became more specialized and thus the specialized classes should be bottom to the general ones.
Option C is rejected because hierarchy works from top to bottom not from left to right.
Option D is not answer because hierarchy has nothing to do with left and right.
Pick two programming languages. Please describe: - The major differences between those two languages; and - If you were assessing an application and determining what language would be best for the programming, why you would choose each language.
First language : JAVA
Second Language : C++
Major Difference :
1. Platform Dependency :
Java is platform independent which means that its code can be run on any machine. It uses JVM ( Java virtual machine ) which converts the code in byte form and then run it which makes it flexible enough to be used on any system. So .exe file can run on any OS.
C++ is not platform independent and thus its .exe file cannot be run on different OS.
2. Objects
In JAVA everything is reference typed and is inherited from the class objects that are predefined in it.
In C++ not everything is class or reference typed.
3. Garbage Collector
Java has built in garbage collector when we use classes in java.
C++ make developer to collect garbage when he uses reference types like pointers.
Why choose Java and C++ ?
People are very confused about the platform in-dependency of JAVA, so i decided to choose Java and compared that concept with c++ which is mother of all languages.

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.

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.

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.

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.

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.
