Which of the following will read values from the keyboard into the array?
(Assume the size of the array is SIZE).
A)cin >> array;
B)cin >> array[ ];
C)for(i = 0;i < SIZE;i ++)
cin >> array[i];
cD)in >> array[SIZE];
Answers
The statement that reads values from the keyboard into the array is "for (i = 0; i < SIZE; i++) cin >> array[i];".Thus, option C is correct.
The elements of an array are either initialized during declaration or during runtime. However, when initializing the values during the runtime, we use a loop that accepts values from the keyboard for each element of the array. The standard approach is to use a for loop that assigns values to array elements.
Here is the standard syntax of the for loop:for (i = 0; i < SIZE; i++) cin >> array[i];As seen in the code snippet, the for loop reads in data for each element in the array. Hence option C is correct.

Disruptive Innovation is the process by which technology enables entrants to launch inexpensive and more accessible products that work collectively with today's comparable market offerings. 5) None of the above. 4)
Answers
Evolution of technology helps the entrants more than the incumbents because entrants can use technology to target customers that do not currently have solutions. Entrants can create technology faster than incumbents, and they are not limited by legacy systems that incumbents are stuck with.
They have the agility to innovate and change direction as necessary to keep pace with technological advances. The incumbents are at a disadvantage because they have already established customer bases and a strong reputation, and they are unlikely to be willing to risk losing that by adopting new technology that may not be as reliable as what they already have. So, the evolving technology helps the entrants to compete with the incumbents.
One of the factors that contributes to enterprises becoming successful in the long run is the ability to understand the consumer better and create products that solve their consumers' job. By leveraging the technological core and their business model, businesses can ensure that their products are meeting the needs of their customers. Plan and forecast based on correlated data is another important factor in the success of enterprises.

what application environment provides os and kernel isolation like a traditional vm, but is not managed by hyper-v manager?
Answers
One application environment that provides OS and kernel isolation similar to a traditional virtual machine (VM), but is not managed by Hyper-V Manager, is Docker.
Docker is a popular containerization platform that allows you to create and manage lightweight, isolated containers. Containers are similar to VMs in the sense that they provide an isolated environment for running applications. However, unlike VMs that run on top of a hypervisor, containers share the host system's OS kernel, which makes them more lightweight and faster to start compared to traditional VMs.
Docker achieves isolation by utilizing kernel features such as c groups (control groups) and namespaces. These features allow Docker to restrict resource usage, control access to system resources, and provide separation between containers. Each container runs as an isolated process with its own file system, network stack, and process space, providing a level of isolation similar to that of a VM.
Docker containers are managed through the Docker Engine, which is responsible for building, running, and managing containers. The Docker Engine interacts directly with the host operating system's kernel to create and manage container instances.
So, if you are looking for an application environment that provides OS and kernel isolation like a traditional VM but is not managed by Hyper-V Manager, Docker can be a suitable choice.

To find the name of the designer of spirit pins on the displayed designers worksheet, you would need to first click on cell B3. Then, you would use the index function with a nested match function to locate the designer's name within the range A6:A27, which is the column where the designer names are located.
The exact formula to use would be:
=INDEX(A6:A27,MATCH("Spirit Pins",B6:B27,0))
This formula will search for "Spirit Pins" within the range B6:B27 and then return the corresponding value from the range A6:A27, which is the name of the designer. In this case, the designer of spirit pins would be displayed.
This formula will first search for "Spirit Pins" in the range B6:B27 using the MATCH function, then return the corresponding designer's name from the range A6:A27 using the INDEX function.
