How to use the strconv.AppendQuote() function in Golang

Golang strconv.AppendQuote()

The strconv package’s AppendQuote() method is used to append the double-quoted Go string literal representing s (as generated by the Quote() function) to dst and return the extended buffer.

Syntax

func AppendQuoteRune(dst []byte, r rune) []byte

Parameters

  • dst: This is a byte array to which the double-quoted string is to be appended.
  • s: This is the double-quoted string to be appended.

Return value

The function AppendQuote() returns the extended buffer after appending the double-quoted string.

Code

The following code shows how to use the AppendQuote() function in Golang.

// Using strconv.AppendQuote() Function 
package main
import (
	"fmt"
	"strconv"
)
func main() {
  // Declaring and assigning value
	x := []byte("Quote 1:")
	fmt.Println()
	fmt.Println("Before AppendQuote():", string(x))
	// Using AppendQuote to appending a quote to the x
	x = strconv.AppendQuote(x, `"Keep learning! keep coding!"`)
	fmt.Println()
	fmt.Println("After  AppendQuote()", string(x))
    // Declaring and assigning value
	y := []byte("Quote 2:")
	fmt.Println()
	fmt.Println("Before AppendQuote():", string(y))
	// Using AppendQuote to appending a quote to the x
	y = strconv.AppendQuote(y, `"Shot on strconv.AppendQuote()"`)
	fmt.Println()
	fmt.Println("After  AppendQuote()", string(y))
}

Code explanation

  • Line 4: We add the main package.

  • Lines 6–9: We import the necessary packages.

  • Lines 11–25: We define the main() function and the variables x and y of byte array type, and assign a value to each.

  • Lines 18-20: We pass the variable to the AppendQuote() function, which appends the double-quoted Go string literal.

  • Finally, the double-quoted string is displayed.
