C program to find the sum and average of N numbers

Write a C program to find the sum and average of N numbers.

  #include <stdio.h>
  int main() {
        float data[100], sum = 0.0, average;
        int n, i;

        /* get the no of entries from the user */
        printf("Enter the no of elements:");
        scanf("%d", &n);

        /* get the input entries */
        printf("Enter your inputs:\n");

        /* find the sum of N numbers */
        for (i = 0; i < n; i++) {
                scanf("%f", &data[i]);
                sum = sum + data[i];
        }

        /* calculate the average */
        average = sum / n;

        /* print the outputs - sum, average */
        printf("Sum: %.3f\n", sum);
        printf("Average: %.3f\n", average);
        return 0;
  }

  Output:

  jp@jp-VirtualBox:~/$ ./a.out
  Enter the no of elements:5
  Enter your inputs:
  150
  300
  450
  200
  100
  Sum: 1200.000
  Average: 240.000
