In this video we are going to generate source code for the GoLang Program, How to declare and use slice 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() {
// Declare a slice of integers
var slice []int

// Add elements to the slice
slice = append(slice, 1)
slice = append(slice, 2, 3)

// Print the slice
fmt.Println(slice)
}


Below is the explanation for the program:

In this program, we declare a slice of integers using the syntax var slice []int.
Slices in Go are dynamic arrays with no fixed size, so we don't need to specify the length of the slice upfront.
We then use the built-in append() function to add elements to the slice. The append() function appends one or more elements to the end of the slice and returns the updated slice.
We can use the assignment operator (=) to assign the updated slice back to the original slice variable.

In this example, we first append the integer 1 to the slice using slice = append(slice, 1).
We then append the integers 2 and 3 to the slice using slice = append(slice, 2, 3).

Finally, we print the entire slice using fmt.Println(slice).
When we print a slice using fmt.Println(), it automatically prints all the elements in the slice, enclosed in square brackets and separated by spaces.
