第一个函数
阅读F2C
获取文件名和通道,从文件中读取并在通道中输入。第二个功能
写C2F
获取 2 个通道和文件名,获取每个通道的值并将较低的值保存在输出文件中。我确定有一些语法错误,但我是 GO 新手
package main
import (
"fmt"
"bufio"
"os"
"strconv"
)
func main() {
fmt.Println("Hello World!\n\n")
cs1 := make (chan int)
var nameinput string = "input.txt"
readF2C(nameinput,cs1)
cs2 := make (chan int)
cs3 := make (chan int)
cs2 <- 10
cs2 <- 16
cs2 <- 7
cs2 <- 2
cs2 <- 5
cs3 <- 8
cs3 <- 15
cs3 <- 14
cs3 <- 1
cs3 <- 6
var nameoutput string = "output.txt"
writeC2F (nameoutput,cs2,cs3)
}
func readF2C (fn string, ch chan int){
f,err := os.Open(fn)
r := bufio.NewReader(f)
for err != nil { // not end of file
fmt.Println(r.ReadString('\n'))
ch <- r.ReadString('\n')
}
if err != nil {
fmt.Println(r.ReadString('\n'))
ch <- -1
}
}
func writeC2F(fn string, // output text file
ch1 chan int, // first input channel
ch2 chan int){
var j int = 0
var channel1temp int
var channel2temp int
f,_ := os.Create(fn)
w := bufio.NewWriter(f)
channel1temp = <-ch1
channel2temp = <-ch2
for j := 1; j <= 5; j++ {
if (channel2temp < channel1temp){
n4, err := w.WriteString(strconv.Itoa(channel1temp))
} else{
n4, err := w.WriteString(strconv.Itoa(channel2temp))
}
w.flush()
}
}
这是我收到的错误消息:
prog.go:38: multiple-value r.ReadString() in single-value context
prog.go:65: w.flush undefined (cannot refer to unexported field or method bufio.(*Writer)."".flush)
