Example 3-10. Using goto

There is an indentation error in this example. The return statement in the lines

if (i < 10)
goto repeat; // the dastardly deed
return 0;

should not be on the same level as the 'if' since this statement is always executed.
So the correct indentation would be:

if (i < 10)
goto repeat; // the dastardly deed
return 0;

In the example on delegates, this code snippet is given:

return (String.Compare(s1.name, s2.name) < 0 ?
comparison.theFirstComesFirst :
comparison.theSecondComesFirst);

I believe it should include the function definition:

public Comparison WhichStedentIsFirst(Student s1, Student s2) {
return (String.Compare(s1.name, s2.name) < 0 ?
comparison.theFirstComesFirst :
comparison.theSecondComesFirst);
}

Bottom of 269 and top of 270

On the 2nd paragraph and the tip on page 270, the book talks about the
WhichStudentComesFirst method. However, up to this point, there has not been
anything on the method except for the body of the method that is assumed to be a part
of that method on the bottom of page 269. Looking at Ex 12-1 will show that the code
on the bottom of page 269 is certainly the body of the method WhichStudentComesFirst.
To eliminate confusion, the code listing including the method name should be put on
the bottom of page 269. Besides, just looking at the code on page 269, what does s1
and s2 refer to? Again, it's the need to eliminate confusion and be clear.

First Paragraph

Line Reads:
The DataSet has a collection of tables; you care only about the first one because
you've retrieved only a single record:

It should read:
The DataSet has a collection of tables; you care only about the first one because
you've retrieved only a single table:

In the example, we have selected only a single table into the DataSet not a single
record.

First paragraph

The BugFixAttribute constructor takes three parameters: bugID, programmer and date.
But the text only identifies programmer and date as the positional arameters.
Shouldn't bugID also be identified as such?
