may you please help me code this in c$++?$ please see pictures

Goal of the game is to update or set a board number to $7$

$-$ Game will consist of $3$ or more players

$-$ Each player will be given a game number between $1-6$

$-$ Your player may select their game number

$-$ Other players' game numbers are randomly chosen

$-$ Each turn a player may add their game number to a board number

$-$ Your player will select the board number

$-$ Other players will select a board number that would make $7$ or randomly if not possible.

$-$ Each selection to a board number will increase its value

$-$ If adding that number equals $7$ that player receives a point, and the board number resets to $0$

$-$ If the board number exceeds $7$ the board number will then change to a number between $1-6$

$-$ For example, if the board number was $5$ and the game number added was $3$ the board number will change to $1$ instead of $8.$

$-$ If the board number was $6$ and game number was $4$ the board number will change to $3$ instead of $10$

$-$ Here are the possible scenarios:

$-8$ changes to $1$

$-9$ changes to $2$

$-10$ changes to $3$

$-11$ changes to $4$

$-12$ changes to $5$

$-$ The first player to receive $3$ points wins!
