Learn Go: Variables and Types
Strings

We’ve talked about numeric types so far, but Go offers a few other built-in types. One particularly useful type is called a string. A string is Go’s type for storing and processing text. In a general programming sense, “string” is a term for text of any length, and the name is chosen to evoke a sequence of data.

Below, we declared two string variables:

var nameOfSong string var nameOfArtist string

Afterward, we assign a value to the variables with the = sign. Surround the text you want to store with double-quotation marks (i.e., ", the single-quote ' has a special other meaning and isn’t used to define strings):

nameOfSong = "Stop Stop" nameOfArtist = "The Julie Ruin"

You can use the + operator on strings to join them, this is known as string concatenation. Note that + does not add in additional spaces or punctuation.

var description string description = nameOfSong + " is by: " + nameOfArtist + "." fmt.Println(description) // Prints "Stop Stop is by: The Julie Ruin.

As mentioned before, strings are very useful, so let’s practice using them in our own code.

Instructions

1.

In main.go, create a string variable called favoriteSnack but do not assign a value just yet.

2.

Assign a value to favoriteSnack, make it whatever snack is your favorite!

3.

Using string concatenation, print out the message "My favorite snack is " followed by whatever the value inside of favoriteSnack is.

Be sure to add the trailing space to "My favorite snack is " or else it will render as "My favorite snack isbroccoli" instead of "My favorite snack is broccoli".
