hi *

In the documentation for lambda library from boost_1_33_1, in section "Getting Started"->"Conventions used in this document" said that in all examples implicitly used such declarations:

using namespace std; using namespace boost::lambda;

So the following will work:

for_each(a.begin(), a.end(), std::cout << _1 << ' ');

But how do I have to rewrite the above line of code to have it compiled without "using namespace boost::lambda;" before it?

Thanks in advance.

This isn't really a boost question, but: boost::lambda::for_each(a.begin, a.end(), std::cout<< _1 << ''); should work. Huh, does it work for you? It does not for me.

for_each(a.begin(), a.end(), std::cout << boost::lambda::_1 << ' '); does. And since the OP is "using namespace std;", it's ok to use for_each(a.begin(), a.end(), cout << boost::lambda::_1 << ' '); Cheers, Filip
