Golang : Append and add item in slice
Problem :
You need to append/add new element into a existing slice. How to do that?
Solution :
Use the builtin function append()
. For example :
package main
import (
"fmt"
)
var a = make([]int, 8)
func AddElement(slice []int) []int {
newSlice := append(slice, 8) //<--- here!
return newSlice
}
func main() {
for i := 0; i < 8; i++ {
a[i] = i
}
fmt.Println("Before :", a)
newa := AddElement(a)
fmt.Println("After :", newa)
}
Output :
Before : [0 1 2 3 4 5 6 7]
After : [0 1 2 3 4 5 6 7 8]
