How can I iterate over a string in Go?

How can I iterate over a string in Go?

In Go, you can use a for loop with the range keyword to iterate over a string. Here's an example:

str := "Hello"
for index, char := range str {
    fmt.Printf("Index: %d, Character: %c\n", index, char)
}

What if I want to get the byte values instead of characters?

You can iterate over the string using a regular for loop to get the byte values. Here's how:

str := "Hello"
for i := 0; i < len(str); i++ {
    fmt.Printf("Index: %d, Byte: %d\n", i, str[i])
}

Can I use a function to process each character?

Yes, you can define a function and call it within the loop. For example:

func processChar(c rune) {
    fmt.Printf("Character: %c\n", c)
}

str := "Hello"
for _, char := range str {
    processChar(char)
}

Are there any built-in functions for string manipulation?

Yes, Go has a package called strings that provides many useful functions for string manipulation, like strings.ToUpper, strings.Contains, and more.
