Answer:

In C++:

#include<iostream>

using namespace std;

int main(){

int numDays;

cin>>numDays;

cout<<"Days: "<<numDays<<endl;

return 0;

}

Explanation:

This line declares numDays as integer

int numDays;

This line gets user input for numDays

cin>>numDays;

This line prints the required output and ends with a newline

cout<<"Days: "<<numDays<<endl;

A user called to inform you that the laptop she purchased yesterday is malfunctioning and will not connect to her wireless netwo

Aloiza [94]

Answer:

B. Have the user press the appropriate function key combination to enable the wireless radio and then attempt to connect to the wireless network.

Explanation:

Every more often than not, users may experience wireless connection problems. How they respond to these issues solely depends on various factors. When a user like this has issues connecting to the network, first on the list of proper troubleshooting procedures is to check whether the wireless adapter or the function key that turns the wireless radio connection on is toggled on. Sometimes the most obvious causes are the hardest to see. The user should check this first because it will save him or her lots of troubleshooting time if the switch was simply physically disabled.

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation

weqwewe [10]

Answer:

speed and storage

Explanation:

The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.

Array Implementation:

Pros: Much Faster and Easier to target a specific element
Cons: Much More Space needed

Linked Implementation

Pros: Less overall space needed
Cons: Much slower speed.

Write an if/else statement that compares the double variable pH with 7.0 and makes the following assignments to the int variable

levacccp [35]

Answer:

if (pH<7.0){

neutral=0;

base=0;

acid=1;

}

else if (pH>7.0){

neutral=0;

base=1;

acid=0;

}

else if (pH==7.0){

neutral=1;

base=0;

acid=0;

}

Explanation:

As required by the question, if and else statements have been used to test the value of the pH and assign the apropriate values to the variables neutral, base and acid.

The code snippet below can be used to prompt the user to enter values for pH

import java.util.Scanner;

public class pHTest {

public static void main(String[] args) {

Scanner scr = new Scanner(System.in);

System.out.println("Enter a value for the pH");

int neutral, base, acid;

double pH = scr.nextDouble();

if (pH<7.0){

neutral=0;

base=0;

acid=1;

}

else if (pH>7.0){

neutral=0;

base=1;

acid=0;

}

else if (pH==7.0){

neutral=1;

base=0;

acid=0;

}

} }
