Golang program to merge two arrays into third array

Here, we are going to learn how to merge two arrays into third array in Golang (Go Language)?
Submitted by Nidhi, on March 07, 2021

Problem Solution:

In this program, we will create two integer arrays and then merge both arrays into 3rd array. After that, we will print the merged array on the console screen.

Program/Source Code:

The source code to merge two arrays into 3rd array is given below. The given program is compiled and executed successfully.

// Golang program to merge two arrays into 3rd array

package main

import "fmt"

func main() {

	var arr3 [10]int
	arr1 := [...]int{0, 1, 2, 3, 4, 5}
	arr2 := [...]int{6, 7, 8, 9}

	for i := 0; i <= 5; i++ {
		arr3[i] = arr1[i]
	}

	var j int = 6
	for i := 0; i <= 3; i++ {
		arr3[j] = arr2[i]
		j = j + 1
	}

	fmt.Println("Merged array: ")
	for i := 0; i <= 9; i++ {
		fmt.Printf("%d ", arr3[i])
	}
}

Output:

Merged array:
0 1 2 3 4 5 6 7 8 9

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created two arrays arr1 and arr2 initialized with few elements. Then we copy the elements of arr1, arr2 into arr3. After that, we printed the elements of merged array arr3 on the console screen.
