Implementing an average counter for an array

  1. Mar 10, 2006 #1
    i need to get this array to calculate the numbers that are less than the average and greater than or equal to the average.

    first of all, i need to figure out how to make a counter to count the average of the array! i can't find the code in the textbook

    here's what i have so far:
    Code (Text):
    #include <stdio.h>
    #define MAXARR 20

    main()
    {
        int
            arr[MAXARR], i, counter, value, no_of_elements, max,sum;
        /*----------------------------------------------------------------------*/
        /* User is requested to enter values from keyboard until -1 is entered  */
        /*----------------------------------------------------------------------*/
        printf("\f");
        counter = 0;
        printf("Do not entere more than %d values\n\n",MAXARR);
        printf("Enter value (-1 to quit): ");
        scanf("%d", &value);
        while (value != -1)
        {
            arr[counter]=value;
            printf("Please enter value (-1 to quit):   ");
            scanf ("%d", value);
            counter = counter + 1;

        }

        /*----------------------------------------------------------------------*/
        /* Output routine.  The number of elements entered is displayed         */
        /*----------------------------------------------------------------------*/
        no_of_elements = counter;
        printf("%d values were entered\n",no_of_elements);
        printf("these values are: \n");
        for(i=0;i<no_of_elements;i=i+1)
            printf("%d  ",arr[i]);

    Code (Text):

    int sum=0;

    for(int count=0; count<counter; count++)
    {
       sum += arr[count];
    }

    double avg = sum/counter;
     
    There's probably more efficient ways, but this is the easiest one I know of. From there, its a matter of another loop through the whole array and a simple if-else statement.
