You really need to find an indentation style you like and use it consistently. Your code as presented is almost unreadable.

You need to re-post correctly formatted code or you will get few if any people that will try to read your code.

thanks~ am sure that I will like it .

Go to your reserved function and let your editor indent it properly. Once you do that, it will look something like this:
```
int  reserved()
{

    for (int k=0;k<m;k++)
        if (reserve[k].id==0);
    {
        reserve[k].id++;
        return reserve[k].id;
    }
    // ...
```
Notice how the opening brace after the if is indented to the left of the if? That's because it's not connected to the if. The if is followed by a semicolon, so it has no body.

The opening brace opens a local block that is outside of the if and more importantly outside of the for-loop. And since it's outside of the for loop k is not in scope.

PS: In the future you really should mention the line number that you get the given error or warning on (plus the complete warning/error message). And properly indent your code, so it's easier to read and you avoid mistakes like this in the first place.
I got it ,and thanks~ for the PS I will do it next time
