史萊姆論壇 - 一個小遊戲的程式該怎麼寫???

可以請問一下下面的小遊戲該怎麼寫呢.......

有高手可以借我參考一下嗎........

感激不進!! :on_22:

Create a tic-tac-toe game.

(1) First display a welcome message to the game. A player enters her or his name, selects to play first or not, and then start to plays the game.
(2) Display a 3 by 3 tic-tac-toe board.
(3) The player selects the cell to mark. The computer randomly selects the cell to mark.
(4) The game is continuing until there is a winner or the game is tie.
(5) Display the winning points for the winner which are the total of 3 different numbers between 1 and 9 random generated by the computer.
(6) The player can choose to continue a new game.

Hint: Refer to the following code.
welcome (char name[]) {
printf("===========================================\n");
printf("Welcome to the tic-tac-toe game! \n");
printf("Your name: ");
scanf("%s", name);
printf("%s, welcome to the game!\n", name);
printf("===========================================\n");
}

draw_box() {
char box[3][3] = {{'+', '-', '+'}, {'|', ' ', '|'}, {'+', '-', '+'}};
int i, j;

for (i = 0; i < 3; i++) {
for (j = 0; j < 3; j++) printf("%c", box[i][j]);
printf("\n");
}
}

main() {
char name[40];

welcome(name);
draw_box();
}

A possible run may look like as follows:
===========================================
Welcome to the tic-tac-toe game!
Your name: Rita
Rita, welcome to the game!
===========================================
a b c

Rita's step => 2b /* input by the user */
