Runes
Runes, also referred to as Characters, represent a single Unicode character. They are declared using the rune
keyword:
index.go
It's important to note that rune values are always enclosed in single quotes ('
). Therefore, we wrote 'a'
.
Note
Unicode is a standard that assigns a unique numerical value to each character, allowing computers to represent and process text from various languages and scripts. While it's not necessary to have an in-depth knowledge of Unicode, you can find more information on the official website.
Now, if we attempt to print the value, we might obtain an integer as output:
index.go
This is because the corresponding decimal value for the character a
in the Unicode system is 97
. You can find a list of Unicode characters and their decimal values here.
Please note that a rune can represent only a single character at a time; therefore, the following is incorrect:
index.go
