int from string in go

Question

What's the function to create a int value from string

i := ???.????( "10" )

Answer 1

Import the strconv package (src/pkg/strconv), then use strconv.Atoi("10")

Answer 2

Some other options:

package main
import "fmt"

func main() {
   var n int
   fmt.Sscan("100", &n)
   fmt.Println(n == 100)
}

package main
import "strconv"

func main() {
   n, e := strconv.ParseInt("100", 10, 64)
   if e != nil {
      panic(e)
   }
   println(n == 100)
}
