Chapter 6:
pg 124: Replace the first paragraph of 6.2.4 by: "The bitwise logical operators &, |, ^, ~, >>, and << are applied to objects of integral types and enumerations - that is, bool, char, short, int, long, unsigned counterparts, and enums. The usual arithmetic conversions (C.6.3) are performed to determine the type of the result."

Chapter 8:

pg 283 /const max_matrix_temp = 7;/const int max_matrix_temp = 7;/
pg 284 Clarification: Replace the first paragraph of 11.7.1 by
"By default, a single argument constructor also defines an implicit conversion. For some types, that is ideal. For example, a complex can be initialized with an int:
complex z = 2; // initialize z with complex(2)In other cases, the implicit conversion is undesirable and error-prone. For example, if we could initialize a string with an int size someone could write:
string s = 'a'; // make s a string with int('a') elements
It is quite unlikely that this was what the person defining s
meant."

}
pg 489 replace "Erasing end() is harmless." by "A call m.erase(b,e) where e is m.end() is harmless (provided b refers to an element of m or is m.end()). However, a call m.erase(p) where p is m.end() is a serious error that could corrupt the container."

pg 528 better:

I p = search(quote.begin(),quote.end(),s.begin(),s.end()); // find s in quote
return p!=quote.end();

{
return transform(first,last,res,identity< iterator_traits< In>::value_type>); // see sec19.2.2
}
The the explicit qualification of identity
is needed to get a specific function from the function template.
The iterator_traits template (19.2.2) is used to get In's element type.

pg 856 s/Like a member, a friend declared within a template is itself a template and is defined using the template parameters of its class./ The <> after the function names indicates that these friend functions are supposed to be template functions./ (late standards change)
pg 863 replace the bottom example by
template< class T> void sort(vector< T>& v)
{
sort(v.begin(),v.end()); // use standard library sort() (without explicitly saying std::)
}
class Container {
vector< int> v; // elements
public:
void sort() // sort elements
{
::sort(v); // sort(vector< int>&) which calls std::sort() rather than Container::sort()
}
// ...
};
Had sort(vector< T>&) called sort() using the std::sort()
notation, the result would have been the same and the code would
have been clearer.
pg 867 advice [5]: Use keywords and digraphs to represent programs on systems where {, }, [, ], |, or ! are missing and trigraphs if \ is missing; C.3.1.
