Hi Yu,

I happen to have finished reading lambda docs just a while ago... :-)

std::cout << (_1 + _2)(boost::lambda::make_const(10), boost::lambda::make_const(10)); std::cout << std::endl;

does the job. You have to be careful about passing constants as arguments, see docs for details. As for std::endl, the problem is that the resulting value (result of std::cout << _lambda_expression_) has some special type. There are some workarounds, try googling on that if this worries you.

Cheers, Filip

Hi,

Thank you for your pointer. I don't have enough time to read through all the manual. Can you point to me which particular section I should read for this problem?

Thanks, Peng
