Explanation / Answer

Both the source code and input data file are suppose to stored in current folder.

#include <stdio.h>
#include <string.h>

int main()
{
    FILE* fp;
   double A, total;
   int i,counter=0;

if ((fp = fopen("input.dat", "r")) == NULL)
{ /* Open source file. */
    perror("fopen source-file");
    return 1;
}
    printf("N1 N2 N3 N4 SUM AVERAGE ");
while(!feof(fp))
{  
    fscanf(fp,"%lf",&A);
    printf("%lf ",A);    
   counter++;
   total=total+A;
   if(counter%4==0)
   {
   printf("%lf ",total);
   printf("%lf",total/4);
   printf(" ");
   total=0;
