How to append elements to slice in GoLang 1.20
0In this video we are going to generate source code for the GoLang Program, How to append elements to 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 an empty slice of integers
slice := []int{}
// Append a single element to the slice using the append() function
slice = append(slice, 1)
// Append multiple elements to the slice using the append() function
slice = append(slice, 2, 3, 4)
// Append the elements of another slice to the first slice using the ... operator
slice = append(slice, []int{5, 6, 7}...)
// Print the final contents of the slice
fmt.Println(slice)
}
Below is the explanation for the program:
In this program, we start by declaring an empty slice of integers using the syntax slice := []int{}.
We then use the append() function to add elements to the slice in three different ways:
Appending a single element: slice = append(slice, 1)
Appending multiple elements: slice = append(slice, 2, 3, 4)
Appending the elements of another slice: slice = append(slice, []int{5, 6, 7}...)
In the third case, we use the ... operator to expand the elements of the second slice and pass them as individual arguments to the append() function.
After appending all the elements, we print the final contents of the slice using the fmt.Println() function.
Note that the append() function returns a new slice with the appended elements,
so we need to assign the result back to the original slice variable.
Also, keep in mind that the append() function may allocate a new underlying array if the current array is full, which can be a performance consideration in some situations.
