C program to find sum and average of n numbers stored in an array

Algorithm

Input: Input size of the array and elements of the array
output: Displays the sum and average of input elements

  1. Start
  2. Input the size of the array say n and enter the elements of the array a[n]
  3. i = 0
  4. sum = 0
  5. while ( i<n )
    5.1 sum = sum + a[ i ]
    5.2 i++
  6. print " The sum of elements in the array is " sum
  7. avg = sum / n
  8. print "The avg of elements in the array is " avg
  9. stop

C Program

#include <stdio.h>
int main()
{
int n;
float avg,sum=0;
printf("Enter the size of array: ");
scanf("%d", &n);
float a[n];
printf("Enter the elements one by one\n");
for (int i = 0; i<n; i++) {
     scanf("%f", &a[i]);
      }
for (int i = 0; i<n; i++) {
      sum = sum + a[i];
      }
printf("The sum of the array is %f \n", sum);
avg = sum / n;
printf("The average of the array is %f", avg);
}
