This program is to read in a list of integers until the value of -999 is input. Complete the program so that it prints out the number of values read, the total of these values, and the average of these values. 1. Declare the proper variables for the number of values (count), total, and average 2. In the while loop, update your variables after reading a new value 3. Calculate the average 4. Display average, count, and total. The printf statements are already given in the base code. The code I need to edit is below in C programming language.

#include

int main (int argc, char** argv)

{

int val;

/* prompt the user for input */

printf ("Enter in a list of numbers followed by the terminal value of -999\n");

/* loop until the user enters -999 */

scanf ("%d", &val);

while (val != -999)

{

scanf("%d", &val);

}

/* calculate the average of the values read in */

/* display the results */

/* use the following printf statements to display the results */

/* remove the comments */

//printf ("For the list of %d numbers with a total of %d\n", count, total);

//printf (" the average is: %15.5f\n", average);

return 0;

}

#include <stdio.h>

int main()

{

   int val, total = 0, count = 0;

   float average = 0;

   printf ("Enter in a list of numbers followed by the terminal value of -999\n");

   scanf ("%d", &val);

   while (val != -999){

       if(val != -999){

           total += val;

           count++;

       }

       scanf("%d", &val);

   }

   average = (float)total / count;

   printf ("For the list of %d numbers with a total of %d\n", count, total);

   printf (" the average is: %15.5f\n", average);

   return 0;

}

Explanation:

Declare the total, count and average variables

In the while loop:

Add the entered number to the total and increment the count by 1 unless it is -999

Calculate average, divide total by count (Typecast the total as float to get decimal result)

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
