Human centered technology often recommends best practices to computer designers and manufacturers, ...............

Human-Computer Interaction is a study that particularly focuses more on the design of computer technology and the interaction between humans and computers. Since the 1980s when HCI surfaced, it has become a crucial tool in popularizing the idea that the interaction between a user and a computer should resemble a human-to-human, open-ended dialogue. When HCI is done well, a human-centered approach powers the creation of products that resonates more deeply with a certain audience. This will ultimately drive engagement and growth.

Write a program that asks a user to enter a date in month day year format (for example 10 12 2016) and displays the day of the w
AleksAgata [21]

Answer and Explanation:

Using javascript:

function dayof_theweek(){

var TodayDate = window. prompt("enter today's date in the format 'year, month, day' ");

var Datenow=new date(TodayDate);

var Dayofweek=Datenow.getday();

var Days=["monday","Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];

if(Dayofweek==indexOf(Days[Dayofweek]))

{

document.createTextnode(Days[Dayofweek]);

}

}

The program above uses a date object which uses the method getday to get the day of the week(get day returns an integer from 0 to 6).we then use a comparison operator == to test the condition that returned value Dayoftheweek is same with the index of the array Days and then print to a html document. The program may need improvements such as the fact that errors may arise when proper input isn't given, and therefore must be handled.

How do u know when a website doesnt like u?
stira [4]
Honest answer a website does not have feelings so therefore there is no way to tell if a website likes you or not!! The reason it may not load is because your IT provider or maybe to firewalls that are set up on your modem. Sometimes its not that and you just need to keep you computer up to date that way it can get on the websites! Hope i helped

We will use linear interpolation in a C program to estimate the population of NJ between the years of the census, which takes pl
nikklg [1K]

Answer:

See explaination for program code

Explanation:

program code below:

#include<stdio.h>

int main()

{

//file pointer to read from the file

FILE *fptr;

//array to store the years

int years[50];

//array to store the population

float population[50];

int n = 0, j;

//variables for the linear interpolation formula

float x0,y0,x1,y1,xp,yp;

//opening the file

fptr = fopen("njpopulation.dat", "r");

if (fptr != NULL)

{

//reading data for the file

while(fscanf(fptr, "%d %f", &years[n], &population[n]) == 2)

n++;

//prompting the user

int year = -1;

printf("Enter the years for which the population is to be estimated. Enter 0 to stop.\n\n");

while(year != 0)

{

printf("Enter the year (1790 - 2010) : ");

scanf("%d", &year);

if (year >= 1790 && year <= 2010)

{

//calculating the estimation

xp = year;

for (j = 0; j < n; j++)

{

if (year == years[j])

{

//if the year is already in the table no nedd for calculation

yp = population[j];

}

else if (j != n - 1)

{

//finding the surrounding census years

if (year > years[j] && year < years[j + 1])

{

//point one

x0 = years[j];

y0 = population[j];

//point two

x1 = years[j + 1];

y1 = population[j + 1];

//interpolation formula

yp = y0 + ((y1-y0)/(x1-x0)) * (xp - x0);

}

}

}

printf("\nEstimated population for year %d : %.2f\n\n", year, yp);

}

else if (year != 0)

{

printf("\nInvalid chioce!!\n\n");

}

}

printf("\nAborting!!");

}

else

{

printf("File cannot be opened!!");

}

close(fptr);

return 0;

}

OUTPUT :

Enter the years for which the population is to be estimated. Enter 0 to stop.

Enter the year (1790 - 2010) : 1790

Estimated population for year 1790 : 184139.00

Enter the year (1790 - 2010) : 1855

Estimated population for year 1855 : 580795.00

Enter the year (1790 - 2010) : 2010

Estimated population for year 2010 : 8791894.00

Enter the year (1790 - 2010) : 4545

Invalid chioce!!

Enter the year (1790 - 2010) : 1992

Estimated population for year 1992 : 7867020.50

Enter the year (1790 - 2010) : 0

Aborting!!
