import (  
   "fmt"  
   "strconv")  
  
func main() {  
   num, s := 12, "12"  
   //string转int  
   s2i, _ := strconv.Atoi(s)  
   fmt.Printf("%t,%d\n", s2i, s2i)  
   // string转int64  
   s2int64, _ := strconv.ParseInt(s, 10, 64)  
   fmt.Printf("%t,%d\n", s2int64, s2int64)  
   // int转string  
   i2s := strconv.Itoa(num)  
   fmt.Printf("%t,%s\n", i2s, i2s)  
   // int64转string  
   int642s := strconv.FormatInt(int64(num), 10)  
   fmt.Printf("%t,%s\n", int642s, int642s)
