C++ Blackjack code only going to first if statement

I'm trying to code a blackjack game and everything is going smoothly so far but for this bit. No matter what I input into hitStand it always goes to the first if statement and "hits". I would like for if "h" is inputted it "Hits" and if "s" is inputted it "Stands" and, if there is an invalid input, it will tell the user to try again.

I'm still fairly new to C++, so some help would be appreciated.

while (repeat == 0)
            {
                char hitStand;
                cout << "Would you like to HIT or STAND [H/S]";
                cin >> hitStand;
                if (hitStand = "H" || "h")
                {
                    PcardNew = rand() % 13 + 1;
                    cout << endl;
                    cout << "Your new card is: " << PcardNew << endl;
                    if (PcardNew > 10)
                    {
                        PcardNew = 10;
                    }
                    playerTotal = playerTotal + PcardNew; 
                    cout << "Your new total is: " << playerTotal << endl;
                }
                else if (hitStand = "S" || "s")
                {
                    break;
                }
                else
                {
                    cout << "Please enter a valid imput [H/S]" << endl;
                }
            }
