1. INPUT: An input function can be defined as the function in programming that enables or allows the computer take in an input in form of any data type from the user. The input is either stored directly into a variable identifier or processed. A real-life scenario of an input function is taking in food. The intake of any substance into the mouth can be likened to an input function. We take in food into the body through the mouth and this is processed within the body.

Another example of input in a real-life scenario is dumping your trash into the bin. In this case, the bin is taking your trash bag as an input. An input function in programming can take in integers, strings, character, float, arrays or any kind of data type. An input function allows the user send information to the computer using the keyboard, voice, gestures and other forms of communication.

Examples of Input Function using C# programming language

Console.WriteLine("Please type any input from keyboard and press enter:");

string userName = Console.ReadLine();

From the above example, In the first line of code, the compiler asks the user to input anything via the keyboard.

In the second line of code, the compiler takes in whatever the user has typed and stores it as a variable that we defined as userinput.

Example of Input Function Using Python programming language

print('Type in your name:')

username = input()

The first line of code requests that the user types in his name as an input, then Second line of code takes in the input and stores it as a variable declared as username

2. EXECUTION: execution in programming can be described as the process of performing some kind of operation as instructed by the code. This means that the computer reads through the code and performs any operation that it is asked to perform. such execution operation may include arithmetics, iteration, comparison and as many instructions as written in the code.

A real life scenario of execution is when you press the "play" button of an ipod. The ipod executes the "play" action and plays any song within in.

Another example is pressing 2+2 in your calculator and pressing "=" sign. The calculator performs the 2+2 operation and gives a result.

So we can then say that for every execution there is usually a result.

Examples of Execution Function using C# programming language

class ExecuteExample

{

static void Main(string[] args)

{

 int additionop= 100 + 500; 

}

}

In the code above, execution occurs at the highlighted line. The compiler is asked to add the numbers 100 and 500. The act/process of adding both numbers is called EXECUTION.

Example of Execution Function Using Python programming language

print('Type in your name:')

username = input()

print('We just executed, ' + username )

Continuing from our code in the "input example" . As seen in the code above, execution occurs at the point where the computer prints the output of the user's input. In this case the computer prints "we just executed, + whatever value the user had passed as an input."

3. COLLECTION: Collection in programming is used to describe the process where a computer objects collects and groups similar elements to form a single unit. This collection can be a group of similar data types.

A real life example of a collection is a Queue of people at an ATM. This can define the Queue collection type. usually this kind of collection is considered as a First in First out collection.

Another example of collection can be a List of cars in a Ford car garage. This garage takes in a range of cars that are Ford models only.

Example of Collection Function using C# programming language

List : A List is a type of collection as seen below:

var listcollect = new List<string>(); 

listcollect .Add("fordexplorer");

listcollect .Add("fordedge");

listcollect .Add("fordescape");

listcollect .Add("fordtruck");

foreach (var car in listcollect)

{

//do somethin

}

The above code creates a collection(list) of the car names as a string in a tipper garage, adds elements(items) to this list and iterates through the list. This is a typical example of a collection.

Example of Collection Function using C# programming language

Queue: a queue is a case of colleciton that uses the first in first out idea. The first in first out concept is : first element to be taken in is pushed out first also known as FIFO:

class ExmapleofQueue

{

static void Main(string[] args)

{

 Queue sampleQueue= new Queue(); 

sampleQueue.Enqueue(1);

sampleQueue.Enqueue(2);

sampleQueue.Enqueue(3);

foreach (Object numberel in sampleQueue)

{

//do something

}

}

From example above, we can see that we created a queue called sampleQueue. This holds a queue of integers.

Discuss whether design considerations need to change for each kind of computer users. support your answer with an example.

vaieri [72.5K]

Each kind of computer users have different knowledge, needs and requirements. For example there is a difference between the computer knowledge of developers and users without technical experience. Because of this, but also why they need and use computers, and what tools they need, design consideration need to change for each kind of computer users.

Which of the following are incorrect? Group of answer choices An interface can contain constructors. You may declare a final abs

spin [16.1K]

Answer:

Explanation:

1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).

2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.

3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.

4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
