Hi, Marshall

IIUC, I found some mistakes in the documentation of 'equal' and 'mismatch'.

http://www.boost.org/doc/libs/1_54_0/libs/algorithm/doc/html/algorithm/CXX14... http://www.boost.org/doc/libs/1_54_0/libs/algorithm/doc/html/the_boost_algor...

In the first code block,

auto seq1 = { 0, 1, 2 }; auto seq2 = { 0, 1, 2, 3, 4 };

std::equal ( seq1.begin (), seq1.end (), seq2.begin ()); // true std::equal ( seq2.begin (), seq2.end (), seq1.begin ()); // Undefined behavior std::equal ( seq1.begin (), seq1.end (), seq1.begin (), seq2.end ()); // false

The second seq1.begin() in the last line should be seq2.begin() as follows.

std::equal ( seq1.begin (), seq1.end (), seq2.begin (), seq2.end ()); // false

Similarly,

std::mismatch ( seq1.begin (), seq1.end (), seq1.begin (), seq2.end ()); // <3, 3>

should be

std::mismatch ( seq1.begin (), seq1.end (), seq2.begin (), seq2.end ()); // <3, 3>

I just fixed these yesterday ;-) Thanks. -- Marshall Marshall Clow Idio Software mailto:mclow.lists@gmail.com A.D. 1517: Martin Luther nails his 95 Theses to the church door and is promptly moderated down to (-1, Flamebait). -- Yu Suzuki
