Golang：无法理解以下代码的执行方式

Question

Below is the code I have a query upon: I have a single dimentional array a I could not understand when i printing a[0][0] then why it is returning ascii value of the character a:

package main
import (
        "fmt"
)

func main() {

        a := [3]string{"a","b","c"} 

        fmt.Println(a[0][0])
 }

Output: 97

Answer 1

Below is the example of code on how it print ascii

a := [3]string{"a","b","c"} 

for _, rune := range a {
   fmt.Println(rune)// It will print a,b,c
}

since you used a[0][0] in your code it is equivalent

for _, rune := range a {
   fmt.Println(rune[0])// It will print 97,98,99
   // rune is equal to x := 'a'
   // when you write it like x := 'a' and
   // fmt.Println(x) the output is 97
}
