Problem 1: you must write a method for this problem called sentenceAnalyzer Write a program that reads a sentence from the keybo

forsale [732]

Answer:

static void sentenceAnalyzer(String sentence){

int lenOfString = sentence.length()-1;

if(sentence.charAt(lenOfString)=='.'){

System.out.println("Declarative");

}

else if(sentence.charAt(lenOfString)=='?'){

System.out.println("Interrogative");

}

else if(sentence.charAt(lenOfString)=='!'){

System.out.println("Exclamation");

}

else{

System.out.println("Unknown");

}

Explanation:

Using Java programming language

Create the method as required

Obtain the index of the last element using the string length method

Use if and else statements to check if the character at the last index is equal to any of the characters given and print the expected output

see a complete code with the main method below

import java.util.Scanner;

public class num11 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

//Receiving User input

System.out.println("Enter a sentence");

String sentence = in.nextLine();

// Calling the method

sentenceAnalyzer(sentence);

}

static void sentenceAnalyzer(String sentence){

int lenOfString = sentence.length()-1;

if(sentence.charAt(lenOfString)=='.'){

System.out.println("Declarative");

}

else if(sentence.charAt(lenOfString)=='?'){

System.out.println("Interrogative");

}

else if(sentence.charAt(lenOfString)=='!'){

System.out.println("Exclamation");

}

else{

System.out.println("Unknown");

}

}

What is a computer dedicated to a single function, such as a calculator or computer game? A. TabletB. PDAC.ApplianceD. Minicompu

viktelen [127]

Answer:

C. Appliance.

Explanation:

When a device or machine performs a single function or task, it is commonly referred to as an appliance. Examples of such is an iron, a calculator, a computer game, washing machines, refrigerators, e.t.c

A Personal Digital Assistant (PDA), is a device, mostly mobile and handheld, that combines various computing features such as telephoning and networking. An example is a tablet. A PDA performs more than a single function.

Minicomputer is a computer usually small in physical size, that is midway in capabilities and support, between a microcomputer and a mainframe computer. An example is also a tablet and our smartphones. Minicomputers are also dedicated to various functions rather than a single function.

In summary, the option that best describes the situation in the question is an appliance.

Hope this helps!

Write a method swaparrayends() that swaps the first and last elements of its array parameter. ex: sortarray = {10, 20, 30, 40} b

Alexus [3.1K]

In the C programming language, you can't determine the array size from the parameter, so you have to pass it in as an extra parameter. The solution could be:

#include <stdio.h>

void swaparrayends(int arr[], int nrElements)
{
int temp = arr[0];
arr[0] = arr[nrElements - 1];
arr[nrElements - 1] = temp;
}

void main()
{
int i;
int myArray[] = { 1,2,3,4,5 };
int nrElements = sizeof(myArray) / sizeof(myArray[0]);
swaparrayends(myArray, nrElements);

for (i = 0; i < nrElements; i++)
{
printf("%d ", myArray[i]);
}

getchar();
}

In higher languages like C# it becomes much simpler:

 static void Main(string[] args)
 {
int[] myArray = {1, 2, 3, 4, 5};
swaparrayends(myArray);
foreach (var el in myArray)
{
Console.Write(el + " ");
}

Console.ReadLine();
}

static void swaparrayends(int[] arr)
{
 int temp = arr[0];
arr[0] = arr.Last();
arr[arr.Length - 1] = temp;
}
