If you've not read the exposition at Lysator, you might care to do so. It dates back to the mid-90s, and a time when there was no other convenient way to get hold of a copy of the C standard than Schildt's "Annotated C Standard" book. (I have a copy - for that reason.) These days, you can get a PDF of the current standard (C, C++) from ANSI quite easily and cheaply ($18 or so). For C, you can also obtain the current (C99) standard in book form relatively cheaply ($85 or so list); the equivalent book for C++ is also available. These are not tutorials, of course. However, they are the ultimate reference source - I use the C99 standard in PDF form a lot. (If you actually need the C89 standard, then you probably do need the left-hand pages of "The Annotated C Standard"; ignore the right-hand pages unless you know enough to shred the material.)
It used to be that you could find lists of reviews of books at the ACCU web site; as of today, the search facility either isn't working or they've forgotten to review the books cited.
One other point against Mr Schildt. Once you have one of his books, you also have a majority of the material in all his other books. That is, there is a strong similarity between the multitude of different titles. Now, you may take that with a pinch of salt if you wish - if the book was published in the current millennium, there's a chance that it is new and improved. But the advice to avoid his books is sound.
