Why Does My Go Code Throw a 'Cannot Assign String with Single Quote' Error?

Troubleshooting "Cannot Assign String with Single Quote" in Go

Are you encountering the perplexing error regarding string assignment in Go where single quotes trigger errors while double quotes function smoothly? Let's delve into the specifics:

In Go, the difference between characters (Runes) and strings is crucial. A single character is denoted by enclosing it within single quotes, while strings are enclosed within double quotes.

For instance, the following code assigns the character 'h' to the variable a using single quotes:

var a rune
a = 'h' // Rune (character) assignment, no error

On the other hand, to assign a string, you must use double quotes:

var b string
b = "hello" // String assignment, no error

Understanding this distinction is essential for avoiding the error "illegal rune literal" when attempting to assign a string (multiple characters) using single quotes.

Single quotes, as explained above, are used to assign single characters (Runes) in Go. To assign a string, you must adhere to the double quotes convention. Embracing this difference will empower you to effectively manipulate strings in your Go programs.
