How can you use std::setw() with array output? - c++

Question

I am making a blackjack game in C++, and I am trying to print out the players and dealers cards in addition to their sums, capital and so on. However I'm running into an issue with std::setw() when printing out the vector of cards. Here is a code snippet:
int width = 18;
std::cout << std::left << std::setw(width) << "Your cards:";
std::cout << std::left << std::setw(width * 2) << "arr";
std::cout << std::left << std::setw(width) << "Dealers cards:";
std::cout << "arr2" << std::endl;
std::cout << std::left << std::setw(width) << "Your sum:";
std::cout << std::left << std::setw(width*2) << player.sum();
std::cout << std::left << std::setw(width) << "Dealers sum:";
std::cout << dealer.sum() << std::endl;
Where arr and arr2 is there should be number values like 5 2 6 1, but if I print each element separately the with alignment will break. I think for setw() to work it needs to be one block or string, or else the vertical alignment will mess up once the values change. I tried myString.push_back() for each vector value and then printing that, with no luck. I assume I need to find a way to print the string into one element.
This is what it should look like:
Your cards: 5 7 1 2 Dealers cards: 2 1 7 5
Your sum: 21 Dealers sum: 21
Your capital: 100 Dealers capital: 100

I have found a solution. You can use stringstream to add int values to a string with no errors in conversion, this is how I fixed my code:
#include <sstream>
std::stringstream playerCards{};
for (int i{}; i < player.cards.size(); i++) {
playerCards << player.cards[i] << " ";
}
int width = 18;
std::cout << std::left << std::setw(width) << "Your cards:";
std::cout << std::left << std::setw(width * 2) << playerCards.str();
This way the array will get put into a string and will count as one block, which is what I was looking for.
