Errata for Bjarne Stroustrup: A Tour of C++ (3rdd edition), Addison-Wesley, 2022. ISBN 978-0-13-499783-4.
There seem to be a wide variety of opinion how much errata should be posted and how it should be presented. I have decided to post only errata that in my opinion may affect comprehension.
I do correct all typos and minor gramatical issues in future printings, and I may insert minor clarifications in the book. I just don't post them all as errata. All comment and corrections are welcome.
I often use the terse notation: s/old text/new text/
Thanks to all who reported problems.
pg 128 and pg 136: /gsl::string_span/gsl::span<char>/
pg 247: we shouldn't pass pairs of pointer when we can use a span instead, so the example is better written as:
double accum(span s, double init)
// compute the sum of [beg:end) starting with the initial value init
{
return accumulate(s.begin(), s.end(), init);
}
double comp2(vector& v)
{
packaged_task pt0{ accum }; // package the task (i.e., accum)
packaged_task pt1{ accum };
future f0 {pt0.get_future()}; // get hold of pt0's future
future f1 {pt1.get_future()}; // get hold of pt1's future
double* first = &v[0];
auto sz2 = v.size()/2;
jthread t1{ move(pt0),span<double>{first,sz2},0}; // start a thread for pt0
jthread t2{ move(pt1),span<double>{first+sz2,sz2},0}; // start a thread for pt1
// ...
return f0.get() + f1.get(); // get the results
}
