Hi All I started playing with boost::lambda and I need some help or some clarification about it or some hint to better understanding how does it work.
I have this piece of code
using namespace boost::lambda; using boost::lambda::var;
int main(int argc, char** argv) { std::vector< int > myList; myList.push_back(100); myList.push_back(200); int interval = 20;
std::for_each( myList.begin(), myList.end(), ( std::cout << "value: " << _1 << "\n", std::cout << "interval: " << var( interval ) << "\n", var( interval )++ )); }
Instead of std::cout << "value: " << _1 << "\n", do this std::cout << constant("value: ") << _1 << "\n", It's described here: http://www.boost.org/doc/libs/1_40_0/doc/html/lambda/using_library.html#lamb... . By the way, if you are just starting with lambda, it's better to use Boost.Phoenix instead. Roman Perepelitsa.
