print elements of a 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: print a 3d vector in c++

// A recursive function able to print a vector
// of an arbitrary amount of dimensions.
template<typename T>
static void show(T vec)
{
  std::cout << vec;
}


template<typename T>
static void show(std::vector<T> vec)
{
  int size = vec.size();
  if (size <= 0) {
    std::cout << "invalid vector";
    return;
  }
  std::cout << '{';
  for (int l = 0; l < size - 1; l++) {
    show(vec[l]);
    std::cout << ',';
  }
  show(vec[size - 1]);
  std::cout << '}';
}
