How do I use for_each to output to cout?

Question

Is there a more straight-forward way to do this?

for_each(v_Numbers.begin(), v_Numbers.end(), bind1st(operator<<, cout));

Without an expli

yup, using lambda expression (C++ 11) we can inline printing of each element of a STL container to cout.

#include    // cout
#include      // vector
#include   // for_each
#include    // istream_iterator
using namespace std;

int main()
{
   std::vector v(10,2);
   std::for_each(v.begin(), v.end(), [](int i)->void {std::cout << i <

For reading "n" values from cin to vector,

 int main()
 {
   std::vector v;

   int elementsToRead;
   cin>>elementsToRead;  // Number of elements to copy

   // Reading from istream
   std::istream_iterator ii2(std::cin);
   std::copy_n(ii2, elementsToRead, std::back_inserter(v));

   // printing updated vector
   std::for_each(v.begin(), v.end(), [](int i)->void {cout << i <

(or) by using Lambda expression

std::for_each(std::istream_iterator(cin),std::istream_iterator(),[&v](int i)->void { v.push_back(i);});
