Go Program to Add Two Arrays

In this Go Program to add two arrays, we allow users to enter the size and the array items. Next, we used for loop (for i = 0; i < size; i++) to iterate the array items from 1 to size. Inside the loop, (additionArr[i] = addArr1[i] + addArr2[i]) we added the two array items at each index position.

package main

import "fmt"

func main() {
    var size, i int

    fmt.Print("Enter the Array Size = ")
    fmt.Scan(&size)

    addArr1 := make([]int, size)
    addArr2 := make([]int, size)
    additionArr := make([]int, size)

    fmt.Print("Enter the First Array Items to Perform Addition = ")
    for i = 0; i < size; i++ {
        fmt.Scan(&addArr1[i])
    }

    fmt.Print("Enter the Second Array Items to Perform Addition = ")
    for i = 0; i < size; i++ {
        fmt.Scan(&addArr2[i])
    }

    fmt.Print("The Sum or Addition of Two Arrays = ")
    for i = 0; i < size; i++ {
        additionArr[i] = addArr1[i] + addArr2[i]
        fmt.Print(additionArr[i], "  ")
    }
    fmt.Println()
}

Enter the Array Size = 5
Enter the First Array Items to Perform Addition = 1 2 3 4 5
Enter the Second Array Items to Perform Addition = 5 9 11 7 10
The Sum or Addition of Two Arrays = 6  11  14  11  15 

Go Program to Add Two Arrays Example 2

In this Golang example, we used the for loop range (for x, _ := range addArr1) and performed the addition. You can also rewrite the for loop as (for x := range addArr1). To show you the syntax, we left that _. 

package main

import "fmt"

func main() {
    var i int

    var addArr1 [5]int
    var addArr2 [5]int
    var additionArr [5]int

    fmt.Print("Enter the First Array Items to Perform Addition = ")
    for i = 0; i < 5; i++ {
        fmt.Scan(&addArr1[i])
    }
    fmt.Print("Enter the Second Array Items to Perform Addition = ")
    for i = 0; i < 5; i++ {
        fmt.Scan(&addArr2[i])
    }
    fmt.Print("The Sum or Addition of Two Arrays = ")
    for x, _ := range addArr1 {
        additionArr[x] = addArr1[x] + addArr2[x]
        fmt.Print(additionArr[x], "  ")
    }
    fmt.Println()
}

Enter the First Array Items to Perform Addition = 3 5 7 9 11
Enter the Second Array Items to Perform Addition = 22 99 88 9 3
The Sum or Addition of Two Arrays = 25  104  95  18  14  

In this Golang program, to add two arrays, we used for loop range to insert and add the array items.

package main

import "fmt"

func main() {
    var size int

    fmt.Print("Enter the Multiplication Array Size = ")
    fmt.Scan(&size)

    addArr1 := make([]int, size)
    addArr2 := make([]int, size)
    additionArr := make([]int, size)

    fmt.Print("Enter the First Array Items to Perform Addition = ")
    for i := range addArr1 {
        fmt.Scan(&addArr1[i])
    }
    fmt.Print("Enter the Second Array Items to Perform Addition = ")
    for j := range addArr2 {
        fmt.Scan(&addArr2[j])
    }
    fmt.Print("The Sum or Addition of Two Arrays = ")
    for x := range additionArr {
        additionArr[x] = addArr1[x] + addArr2[x]
        fmt.Print(additionArr[x], "  ")
    }
    fmt.Println()
}
