In this article, we are going to learn about find average of numbers stored in array in go golang. Average is the sum of numbers divided by total numbers.
Example:
Numbers = 1, 2, 3, 4, 5
Sum of these numbers : 15
Total number: 5
Average: 15 /5 = 3
Algorithm:
- Get the size of array elements from user
- Store the elements into array
- Get the sum of array elements
- Calculate the average of array elements
Formula to calculate the average number:
avg = sum of total numbers / total numbers
Example with Code in golang:
package main
import "fmt"
func main() {
// Declare the array size
var array_size int
fmt.Println("Enter the size of array: ")
fmt.Scan(&array_size)
fmt.Println("Enter the array elements: ")
// Create the array
array := make([]int, array_size)
sum := 0
for i := 0; i < array_size; i++ {
fmt.Scan(&array[i])
// Calculate the sum of array elements
sum = sum + array[i]
}
// Calculate the average of array elements
avg := float64(sum) / float64(array_size)
fmt.Printf("\nAverage is : %f", avg)
}
Output:
Enter the size of array:
6
Enter the array elements:
1
2
3
4
5
6
Average is : 3.500000
