Program/Source Code:

The source code to create a slice using the make() function is given below. The given program is compiled and executed successfully.

// Golang program to create a slice using
// the make() function

package main

import "fmt"

func main() {

	// Creating an array of size 8 and slice this array
	// till 5 and return the reference of the slice
	var slice = make([]int, 5, 8)

	fmt.Println("Slice: ", slice)
	fmt.Println("Length of Slice: ", len(slice))
	fmt.Println("Capacity of Slice: ", cap(slice))
}

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 and slice the array for 5 elements using the make() function, and then printed the slice, length, capacity on the console screen.
