Explain How to Split a Slice of bytes in Go Language | Go Programming Tutorial
In this article, you will learn how to split a slice of bytes in Go Programming Language.
A slice is a kind of data type which is similar to an array which is used to hold the items of the same data type. The only difference between array and slice data types is that slice can vary in size dynamically but it is not feasible in arrays.
In the GoLang slice of bytes, the user is allowed to split the given slice using a split() function. The split() function helps in splitting a slice of the byte into all the sub-slices separators and returns a slice that contains all these sub-slices. It is defined under the bytes package so, the user has to import the bytes package in the program for accessing split() function.
Syntax:
func Split(org_slice, dif [ ]byte) [ ] [ ] byte
Here, org_slice is the slice of bytes and dif is the separator. If the dif is empty, then it will split after the UTF-8 sequence.
Example:
package mainimport ( "bytes" "fmt") func main() { // Create and initializethe slice of bytes // Using shorthand declaration s_1 := []byte{'!', 'T', 'u', 't', 'o', 'r', 'i', 'a', 'l', 's', 'L', 'i', 'n', 'k', '#'} s_2 := []byte{'E', 'b', 'o', 'o', 'k', 's'} s_3 := []byte{'%', 'H', '%', 'o', '%', 'm', '%', 'e, '%'} // Displaying slices fmt.Println("Original Slice:") fmt.Printf("Slice 1: %s", s_1) fmt.Printf("\nSlice 2: %s", s_2) fmt.Printf("\nSlice 3: %s", s_3) // Splitting the slice of bytes // Using Split function res1 := bytes.Split(s_1, []byte("link")) res2 := bytes.Split(s_2, []byte("")) res3 := bytes.Split(s_3, []byte("%")) // Display the results fmt.Printf("\n\nAfter Splitting:") fmt.Printf("\nSlice 1: %s", res1) fmt.Printf("\nSlice 2: %s", res2) fmt.Printf("\nSlice 3: %s", res3) }
