All chapter 4

Hello,

(The problem does not concern page 4, but chapter 4 examples. I haven't browsed the other chapters
yet.)

The uses of stream.eof() and getline are incorrect. The lines should be read with:
while(std::getline(in, tmp, '
'))

see http://www.parashift.com/c++-faq-lite/input-output.html#faq-15.5

Top third of the page in the Tip, suggestion or general note section

The Tip reads as follows:

Before you start working through the recipes in this chapter, create four sibling directories
johnpaul, geogreringo, hellobeatles, and binaries...

The directory geogreringo is later referenced as georgeringo (which I suspect is the correct name).

Example 2-1

In example 2-1 and all following examples, you use

FILENAME_H__ as the include guard.

However, the C++ Standard ISO/IEC 14882:2003 explicitly reserves to the implementation all
identifiers containing a double underscore.

The include guards in the examples should simply use a single trailing underscore:

FILENAME_H_

half way down

The output shown for example 3-4 should be:
There are 3 ways to do this.
There are Those cost $50.
abc123

rather than:
There are 3 ways to do this.
Those cost $50.
abc123

I ran this example and researched the boost format.hpp and discovered that the code line f.clear()
clears the bound items not the object f as it was declared. so the no bound items. so everything
from %1% on in the declaration of f is cleared.

I compiled the code on MinGW 3.4.2 compiler using Eclipse CDT as my IDE.

Example 4-10

The function
void split(...)
you show in this example will fail, if the string does not contain the separator character. The resulting vector<string> will not contain any entries, while I would expect it to contain one entry, the full input string.
A possible solution (add lines marked with a +):
void split(const string& s, char c,
vector<string>& v) {
string::size_type i = 0;
string::size_type j = s.find(c);

+ if (j == string::npos) {
+ v.push_back(s);
+ return;
+ }

while (j != string::npos) {
// ... the while loop as in the example
}
}

in function "loadCSV" 3rd comment line

the comment "// Recipe 4.7" should refer to 4.6, i.e. should read

11th line from bottom

I am not at all a C++ expert so I may have missed something here. However, on page
216 in the initial vector example, the code near the bottom of the page reads:

string s = "Marines";
vector<string>::iterator p = find(strVec.begin(), strVec.end(), s);

if (s != strVec.end()) // Insert s immediately before the element
strVec.insert(p,s); // p points to.

************* With my compiler (Digital MARS - I have others this is just the one I
happened to be playing with - it coughs on the s != strVec.end() statement. I think
this is because the statement should read: if (p != strVec.end()) .... as the
iterator should be used.

First three lines in Example 8-12, second page

As is, this code generates malloc errors when run, the reason being that the recursive delete tries
to delete a pointer that is really a pass by reference.

This can be fixed by using

TreeNode<string>* node1 = new TreeNode<string>("frank");
....

node1->addChild(node2);

This problem, however, is something that might merit discussion as it had me confused for a bit.

Function writeTableRow

Newer versions of gcc (3.4 and above) require "typename" to be inserted before
vector<valT>::const_iterator in the declaration of the for loop.

original:
for (vector<valT>::const_iterator p = v.begin( );
changes to:
for (typename vector<valT>::const_iterator p = v.begin( );

Example 10-14. Creating a temporary filename

This is in reference to "10.9 Creating a Temporary Filename and File".

The example recommends using the function tmpnam to create a unique file name. Using this function is discouraged. See the man page.
tmpnam -- "Never use this function. Use mkstemp(3) instead."

'Matricies' should be spelled 'matrices'. Misspelled in several places and in TOC (pg. ix).

paragraphs 1-3

In third paragraph:
"So what actually happens when submitJob calls notify_all is that the waiting
thread..." submitJob does not call notify_all in the example code. It calls notify_one.

Also, paragraphs 1-3 are in need of major editing. I have read this section at least 10 times and I
am still not sure I understand what the author is explaining.

Example 14-26

The example is "Adding support for serialization to the class Animal...", but the
example code shows "class Contact".
The code should be "class Animal"
