What is a straight in cards and how is it formed in a game?

In card games, a straight is a hand that consists of five consecutive cards of any suit. It is formed by having cards in a sequence, such as 2, 3, 4, 5, 6 or 10, J, Q, K, A. Players can form a straight by having the right combination of cards in their hand or by drawing the necessary cards from the deck during the game.
