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) );
}
