Program printing the wrong variable from channel-CodePudding

package main

import "fmt"

func main() {

    c := make(chan int, 5)
    c <- 5
    c <- 6
    close(c)
    fmt.Println(<-c)

}

shouldn't the program above print 6 since it is the last value sent to the channel?

Whay is more, is it possible to print / receiving from a closed channel?

It prints 5

CodePudding user response：

Golang channels are FIFO, first in first out. That is why 5 gets printed out first.

EDIT: Closing channel indicates that no more data will be send to it.

"If a channel is closed, you can still read data. But you cannot send new data into it. This program reads both before and after closing the channel, which works. It’s closed only for sending"
