How to find the sum of an Array/Slice of numbers in Go Language

Given an Array and Slice of Integers, Write a Go Language Program to find the sum of the elements of the Array and Slice.

Note:

Once an Array has allocated its size, the size can no longer be transmuted. 

A Slice is a variable-length version of an Array, providing more flexibility for developers.

A range clause provides a way to iterate over an Array or Slice.

Example 1: Program to find the sum of the elements of an Array using for loop range

package main

import (
    "fmt"
)

func Sum(numb [6]int) int {
    output := 0
    for _, n := range numb {
        output += n
    }
    return output
}
func main() {
    num := [6]int{5, 1, 7, 2, 3, 6}
    fmt.Println("Sum :", Sum(num))
}

Output:

Example 2: Program to find the sum of the elements of a Slice using for loop range

package main

import (
    "fmt"
)

func Sum(numb []int) int {
    output := 0
    for _, n := range numb {
        output += n
    }
    return output
}
func main() {
    num := []int{5, 1, 7, 2, 3, 6}
    fmt.Println("Sum :", Sum(num))
}

Output:

Example 3: Program to find the sum of the elements of an Array using for loop

package main

import (
    "fmt"
)

func Sum(numb [6]int) int {
    output := 0
    for i := 0; i < len(numb); i++ {
        output = output + numb[i]
    }
    return output
}
func main() {
    num := [6]int{5, 1, 7, 2, 3, 6}
    fmt.Println("Sum :", Sum(num))
}

Output:

Example 4: Program to find the sum of the elements of a Slice using for loop

package main

import (
    "fmt"
)

func Sum(numb []int) int {
    output := 0
    for i := 0; i < len(numb); i++ {
        output = output + numb[i]
    }
    return output
}
func main() {
    num := []int{5, 1, 7, 2, 3, 6}
    fmt.Println("Sum :", Sum(num))
}

Output:
