How Do Strings and Characters Differ in Go's Representation?

Understanding String Representation in Go

In Go, like many other programming languages, strings and characters are represented differently. When attempting to assign a single character to a string variable, such as 'a', the Go compiler raises an error due to the difference in character representation.

In Go, '⌘' denotes a single character (a rune), while "⌘" represents a string containing that character. This is similar to other languages like C , where the distinction between strings and characters is crucial.

As mentioned in the Go Blog on Strings, strings are sequences of Unicode code points. A single character can be represented by one code point (a rune), while a string can contain multiple code points. The "Code points, characters, and runes" section of the blog provides a detailed explanation of this distinction.

Additionally, it's important to note that strings in Go are not null-terminated like in C ; instead, they are represented by a pointer to their starting address and an integer representing their length.
