7.golang的字符串 string

golang 字符串为不可变的量 ，字符串定义要使用双引号

package main

import "fmt"

func main() {

	var xx string = 'xxxxxxx'

	fmt.Print(xx)

}

C:/Go/bin/go.exe run main.go [D:/goproject/first/stringxx]

# command-line-arguments

.\main.go:6:6: cannot use '\u0000' (type rune) as type string in assignment

.\main.go:6:18: invalid character literal (more than one character)

package main

import "fmt"

func main() {

	str1 := `func main() {
	// var xxx byte = 'x'
	// fmt.Println(xxx)
	// fmt.Printf("%c", xxx)
	var str2 int
	str2 = 25555
	fmt.Printf("%c", str2)
}
	`
	fmt.Println(str1)
}
