在[for]循环中使用返回值

Question

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?

Answer 1

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

    ProcessCommand(command)
}
