go 语言学习记录1

  1 package main
  2 
  3 import "fmt"
  4 
  5 func sum(values [] int , resultChan chan int){
  6     sum:=0
  7     for _, value := range values{
  8         sum += value
  9     }
 10     resultChan <- sum
 11 }
 12 
 13 func main(){
 14     values := [] int{1,2,3,4,5,6,7,8,9,10}
 15     resultChan := make(chan int, 2)
 16     go sum(values[:len(values)/2],resultChan)
 17     go sum(values[len(values)/2:],resultChan)
 18     sum1, sum2 := <-resultChan, <-resultChan
 19 
 20     fmt.Println("Result:",sum1,sum2,sum1+sum2)
 21 }

1 {} 格式要求

2 package main ， func main

3 默认支持gdb

4 函数可返回多个值
