The document describes a program that implements the dice game PIG between two players. It includes functions to print intro text, get player names, roll dice in a player's turn and update scores. The humanTurn function allows a player to roll multiple times in a turn until getting a 1 or choosing to stop. The program runs a loop where players take turns rolling until one reaches or exceeds a winning score of 100.

1. this is what i have. i really need help on updating the scores only. like if a person gets pig on
their second turn their score would be what the have before.
You are to finish the program below that implements the dice game PIG played by 2 human
players.
Pig is a dice game where each player during their turn rolls a 6-sided die. If the player rolls a 2
through 6, they decide whether they want to keep their turn score or roll again. If they roll a 1,
the player loses all the points for that turn, thus receiving a turn score of 0 and that turn is over.
The first player to reach 100 points or more wins.
this is what i have. i really need help on updating the scores only. like if a person gets pig on
their second turn their score would be what the have before.
