how to print element in vector c++ code example

Example 1: c++ print elements of vector to the console

#include <iostream>
#include <vector>

int main()
{
	std::vector<int> myVector = {1, 2, 3, 4, 5, 6};

	for(int i = 0; i < myVector.size(); i++)
	{
		std::cout << myVector[i] << std::endl;
        
        //***** alternate method *******
		//std::cout << myVector.at(i) << std::endl;		
	}	
}

Example 2: c++ print vector without loop

template <typename T>
std::ostream& operator<< (std::ostream& out, const std::vector<T>& v) {
  if ( !v.empty() ) {
    out << '[';
    std::copy (v.begin(), v.end(), std::ostream_iterator<T>(out, ", "));
    out << "\b\b]";
  }
  return out;
}
