问题

我有使用C#的经验，可以处理用户的命令，代码如下：

string command;
while ((command = GetCommandFromUser()) != EXIT_COMMAND)
    ProcessCommand(command);

这段简单的代码允许我从用户那里获取命令（从控制台或类似的地方），并对其进行处理。

但是在Go语言中，我只有以下代码：

var command string
for command = GetCommandFromUser(); command != ExitCommand; command = GetCommandFromUser() {
    ProcessCommand(command)
}

我能简化它吗？

英文:

I have an experience with C#, where I can work with commands from user like this:

string command;
while ( (command = GetCommandFromUser()) != EXIT_COMMAND )
    ProcessCommand(command);

This simple code allows me get command from user (from Console or something like this) and process it.

But in Go I have only this code:

var command string
for command = GetCommandFromUser(); command != ExitCommand; command = GetCommandFromUser() {
	ProcessCommand(command)
}

Can I do it simply?

for {
    command := GetCommandFromUser()
    if command == ExitCommand {
        break
    }

    ProcessCommand(command)
}

for {
    command := GetCommandFromUser()
    if command == ExitCommand {
        break
    }

    ProcessCommand(command)
}

for {
    command := GetCommandFromUser()
    if command == ExitCommand {
        break
    }

    ProcessCommand(command)
}

英文:

for {
    command := GetCommandFromUser()
    if command == ExitCommand {
        break
    }

    ProcessCommand(command)
}
