初学C语言，经过写完这个游戏发现与众多语言有很大差别的，虽说语法都差不多，但不能直接return数组这种让我觉得写C是一项体力活啊
这个游戏规则为呈现一个九宫格，电脑和人两个玩家对玩，只要有任意一方优先连成一条直线（3个）就算赢
算下来赢法一共就有8种，横线3条竖线3条对角线2条
以下是代码
#include <stdio.h>
#include <stdbool.h>
#include <stdlib.h>
#include <time.h>
bool isDone (int arr[9], char a) {
int len = 9;
int len1 = 3;
int correct = 0;
bool isWin = false;
for (unsigned int i = 0; i < len; i++) {
if (arr[i] == a) {
correct++;
}
if ((i + 1) % len1 == 0) {
if (correct == len1) {
isWin = true;
break;
} else {
correct = 0;
}
}
}
for (unsigned int i = 0; i < len1; i++) {
correct = 0;
for (unsigned int j = i; j < len; j+=len1) {
if (arr[j] == a) {
correct++;
}
}
if (correct == 3) {
isWin = true;
printf("\n Here 2");
break;
}
}
