How to declare and use runes in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to declare and use runes using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
##############SOURCE CODE#########################
package main
import "fmt"
func main() {
var r rune = 'A'
fmt.Printf("Rune: %c, Type: %T\n", r, r)
}
Below is the explanation for the program:
In this program, we declare a variable r of type rune and assign it the value of the character 'A', enclosed in single quotes.
We then use the %c format specifier to print out the value of the r variable, which will print the character associated with the rune value.
We also use the %T format specifier to print out the type of the r variable, which should be rune.
When you run this program, you should see output like the following:
Rune: A, Type: int32
This demonstrates how to declare and use runes in Go. The rune type is used to represent a Unicode code point, and can be used to work with strings that contain non-ASCII characters.
