C++ Primer ErrataLast modified 9 October 2012
Every book has bugs in it, and
C++ Primer is no exception.
This page presents all the bugs that have come to our attention.
All of these errors will be corrected in the
Second printing, October 2012.
Many thanks to the careful readers who notified us of these problems!
Technical errors corrected in the second printing
- Page 475:
The begin and end members of class
StrBlob should be defined outside the class body.
They can't be defined until class StrBlobPtr
- Page 522:
The remove_from_Folders member correctly
removes pointers to itself from each of its
corresponding Folders, but it should
clear its own folders member as well.
- Pages 525–528:
The alloc member of StrVec should
be a static member of the class, not a data member
of each object.
To fix this error, add the static
keyword to the declaration of alloc
inside the StrVec class and provide
a definition of the form
inside the implementation file for StrVec.
- Page 567:
In the StrBlobPtr::operator--() function,
the call to check should pass curr as the first
argument, not -1.
- Page 762:
EOF preprocessor variable is defined
in the cstdio header not iostream.
Clarifications and improvements made in the second printing
- Page 175:
The scores vector should be defined as
const because we do not want the elements
in scores to be changed.
- Pages 576–578:
The div class reuses the
name of a C library function.
C++ compilers are permitted to put C library names
into the global namespace.
To avoid potential conflicts
rename this class divide.
- Page 780:
from the last sentence
of the highlighted box titled Backward Compatibility:
These declarations both say that recoup won't throw, but there
are subtle distinctions between what the compiler is permitted to do
with these declarations.
Typographical errors corrected in the second printing
- Pages xxvi and 22 the correct web address for the
book code is http://www.informit.com/title/0321714113
- Page 155:
The explanation of why we use an unsigned long
rather than an int
should say that we need "at least 27" bits, not
that we need "at least 17" bits.
- Page 158: The last sentence before the exercises for 4.10
should say that we
"reset the current element" not the "next element".
- Page 177:
The second comment in the first two code examples should
include 7 as a grade that will get a minus.
- Page 225: In the third sentence before the Tip
box, should read "string named ret"
not "string named s".
- Page 229:
The type alias declaration in the code example at the top of the page
should define arrT not arrtT and the
last comment in that example should
say that "func returns a pointer
to an array of ten ints" not five ints.
- Page 236: Last sentence before the last code example
to override the default for backgrnd,
we must also supply arguments for ht and wid:"
- Page 243:
Replace "parameter" at the end of the last bullet
by "argument in the call".
Changes in exercises made in the second printing
- Page 59:
Exercise 2.25 (a) should be
int* ip, i, &r = i;
- Page 228: Exercise 6.35 replace
- Page 250: Exercise 6.55 change "values" to "functions".
