Golang program to create a new slice from the existing slice

Here, we are going to learn how to create a new slice from the existing slice in Golang (Go Language)?
Submitted by Nidhi, on March 15, 2021

Problem Solution:

In this program, we will create a new slice from an existing slice, which is created from an integer array.

Program/Source Code:

The source code to create a new slice from the existing slice is given below. The given program is compiled and executed successfully.

// Golang program to create a new slice
// from the existing slice

package main

import "fmt"

func main() {
	//Create an array of integers.
	arr := [8]int{1, 2, 3, 4, 5, 6, 7, 8}

	OrgSlice := arr[1:7]
	NewSlice := OrgSlice[1:4]

	fmt.Println("Orginal slice: ", OrgSlice)
	fmt.Println("New slice: ", NewSlice)
}

Output:

Orginal slice:  [2 3 4 5 6 7]
New slice:  [3 4 5]

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 an array of integers with 8 elements. Then we create a slice OrgSlice from the array. After that, we created the NewSlice slice from the OrgSlice slice and then we printed both slices on the console screen.
