Immutable Strings in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, Immutable strings 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.
In this program I have replaced the angled brackets with > or <. once you copy the source code to editor replace it with greater than or less than symbols respectively.
##############SOURCE CODE#########################
package main
import "fmt"
func main() {
str := "hello world"
fmt.Println("Original string:", str)
// Attempt to modify the string
// This will fail because strings are immutable
// Uncommenting the following line will result in a compilation error
// str[0] = 'H'
// Create a new string based on the original
newStr := str[:5] + "WORLD"
fmt.Println("New string:", newStr)
fmt.Println("Original string:", str)
}
##############END OF SOURCE CODE#########################
Below is the explanation for the program:
In this program, we define a string str and attempt to modify its first character to uppercase.
However, we immediately get a compilation error because strings are immutable in Go and cannot be modified once they are created.
To demonstrate this, we create a new string newStr based on the original str by concatenating the first 5 characters of str with the string "WORLD".
We then print both the original and new strings to the console.
Note that the original string remains unchanged despite our attempt to modify it.
This demonstrates the immutability of strings in Go.
