所以我在这个井字游戏中需要一些帮助。我几乎一切都正常工作，我只需要添加一些功能。这些功能包括：1.) 允许玩家选择在游戏中扮演 X 还是 O，以及 2.) 为玩家提供重玩游戏的选项（如果他们愿意）。我已经很好地掌握了游戏的基本机制，但我只是不知道如何将这些功能添加到代码中。我已经开始为第一个功能“奠定基础”（让玩家可以选择自己的标记）。 （老实说，过去 48 个小时的期末考试我真的很累，我真的需要帮助）。这是我的完整代码：
#define _CRT_SECURE_NO_WARNINGS
#pragma warning(disable : 4996)

int checkwin(char gridspace[]);
void gameboard(char gridspace[]);

{
char grid[10] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' };
int player = 1, victory, choice;
char mark, player1, player2;
int markchoice;
do // game loop start
{
gameboard(grid); // draws the game board
if (player % 2) // player turn conditional
{
player = 1;
}
else
{
player = 2;
}
printf("Player 1, choose which mark you would like to play as (1=X or 2=O)\n"); // asks the player to choose a mark
scanf("%c", &markchoice);
if (markchoice == 1) // mark choice conditional
{
mark = 'X';
}
else
{
mark = 'O';
}
printf("Player %d, enter the number of the place you wish to place your mark: ", player); // asks the player to place their mark on a space
scanf("%d", &choice);
if (player == 1) // mark type (X or O) placement conditional
{
mark;
}
else
{
mark;
}
gameLoop(choice, player, grid, mark); // calls the main game function that houses the conditionals
victory = checkwin(grid); // checks the state of the game (if its in progress, a draw, or a player has achieved victory.
player++;
} while (victory == -1); //end of game loop
gameboard(grid); // redraws the game board
if (victory == 1) // conditional that breaks the game loop and gives a result (victory or draw)

任何和所有帮助将不胜感激。所以提前谢谢你！
要允许多轮，您可以在游戏外添加另一个 while 循环，以便重置所有统计数据并重新启动游戏，直到玩家决定停止（您可以使用 scanf 来检查 y/n）。
您可以将 do while 与此结构一起使用：
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
//insert other libraries you need here
int main()
{
do
{
//***insert rest of code here***
printf("Do you want to play again? (Y/N)\n");
char Response;
scanf("%c", &Response);
if(toupper(Response)==N)
{
printf("Thanks for playing!");
break;
}
}while(toupper(Response)==Y);
return 0;
}
***如果有语法错误请告诉我。我从 C 开始，但已经用基本指针编写了 Tic-Tac-Toe。这几乎就是我所做的。
