how to print vector in c++ code example

Example 1: cpp print vector

for(int i = 0; i < vec.size(); i++)
    std::cout << vec[i] << ' ';

Example 2: 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 3: how to use vectors c++

#include <iostream>
#include <vector>
using namespace std;

int main() {
  //vector element size
  const int size = 4; 
  //vector with int data type
  //all elements are equal to 4
  vector<int> myVect (size, 4);

  for (int i=0; i<size; i++) {
    cout << "Vector index(" << i <<") is: "<< myVect[i] << endl; 
  }
  return 0;
}
