Hi,

I am trying to Call for_each with boost::lambda library to print out the return value of a function:

vector<A> aList;

for_each(aList.begin(), aList.end(), cout << bind(&A::getPriority, _1) );

This can't compile. can yo please tell me what did I do wrong?

Without more detail (e.g. error message, what does A look like...), it's difficult to tell.... Here's a minimal example that *does* compile - where is your code different... #include <vector> #include <iostream> #include <algorithm> #include #include using namespace std; using namespace boost::lambda; class A { public: int getPriority() const { return 1; } }; void x() { vector<A> aList; for_each(aList.begin(), aList.end(), cout << bind(&A::getPriority, _1) ); } Stuart Dootson
