How to get first character of a string in Golang
In this post we will give you information about How to get first character of a string in Golang. Hear we will give you detail about How to get first character of a string in GolangAnd how to use it also give you demo for it if it is necessary.
we will learn how to get the first character of a given string in Golang.
In Golang, strings are the character sequence of bytes.
Getting the first character
To access the string’s first character, we can use the slice expression [] in Go.
Here is an example, that gets the first character L from the following string:
country := "London"firstCharacter:= country[0:1]fmt.Println(firstCharacter)
Output:
L
In the example above, we have passed [0:1] to the slice expression. so it starts the extraction at position 0 and ends at position 1 (which is excluded).
Note: The above syntax works on ASCII Characters.
For unicode characters, we can access the first character like this:
str := "😀😁😁"result := []rune(str) // convert string to runesfirstCharacter := string(result[0:1]) // convert runes back to stringfmt.Println(firstCharacter)
Output:
😀
