判断函数
界面函数：
void manu() {
printf("*************************\n");
printf("***** welcome! *******\n");
printf("***** 1:play *******\n");
printf("***** 2:quit *******\n");
printf("*************************\n");
//界面函数只要是用于main函数中循环调用
}
棋盘初始化
void InitChess(char chess[ROW][COL], int row, int col) {
for (int i = 0; i< row; i++) {
for (int j = 0; j< col; j++) {
chess[i][j] = ' ';//初始化为‘ ’方便后续打印
}
}
}
棋盘打印函数
上图为打印界面样式，采用每一个小格打印两行，第一行为“ %c ”加‘|’第二行为---加‘|’，最后一列不打印‘|’，在最后一行中不打印---，由此写成一下循环
void PrintBoard(char chess[ROW][COL], int row, int col) {
for (int i = 0; i< row; i++) {
for (int j = 0; j< col; j++) {
printf(" %c ", chess[i][j]);
if (j< row - 1)//最后一列不打印‘|’
printf("|");
}
printf("\n");
if (i< row - 1)//最后一行不打印---
{
for (int j = 0; j< col; j++) {
printf("---");
if (j< row - 1)
printf("|");
}
printf("\n");
}
}
}
下棋函数
void Player(char chess[ROW][COL], int row, int col) //玩家下棋
{
int row1 = 0;
int col1 = 0;
while (1) {
printf("请输入位置>>");
scanf("%d %d", &row1, &col1);
if (row1 >ROW || row1<= 0 || col1 >COL || col1<= 0) {
printf("pos error\n");
continue;
}
if (chess[row1-1][col1-1] != ' ') {
printf("pose error\n");
continue;
}
else {
chess[row1-1][col1-1] = '#';
break;
}
}
}
void computer(char chess[ROW][COL], int row, int col) //电脑下棋
{
while (1) {
int row1 = rand() % 3;//srand函数在进入函数前调用
int col1 = rand() % 3;
if (row1 >ROW || row1<= 0 || col1 >COL || col1<= 0) {
continue;
}
if (chess[row1 - 1][col1 - 1] != ' ') {
continue;
}
else {
chess[row1 - 1][col1 - 1] = '*';
break;
}
}
}
判断函数
int judge(char chess[ROW][COL], int row, int col) //简易判断，只考虑三子棋，没有写的更加深入
{
for (int i = 0; i< ROW; i++) {
if (chess[i][1] == chess[i][2] && chess[i][2] == chess[i][0] && chess[i][1] == '#') {
return 1;
}
}
for (int i = 0; i< COL; i++) {
if (chess[1][i] == chess[2][i] && chess[2][i] == chess[0][i]&&chess[1][i]=='#') {
return 1;
}
}
if (chess[1][1] == chess[2][2] && chess[2][2] == chess[0][0]&&chess[0][0]=='#')
return 1;
if (chess[0][0] == chess[1][1] && chess[1][1] == chess[2][2] && chess[0][0] == '#')
return 1;
for (int i = 0; i< ROW; i++) {
if (chess[i][1] == chess[i][2] && chess[i][2] == chess[i][0] && chess[i][1] == '*') {
return -1;
}
}
for (int i = 0; i< COL; i++) {
if (chess[1][i] == chess[2][i] && chess[2][i] == chess[0][i] && chess[1][i] == '*') {
return -1;
}
}
if (chess[1][1] == chess[2][2] && chess[2][2] == chess[0][0] && chess[0][0] == '*')
return -1;
if (chess[0][0] == chess[1][1] && chess[1][1] == chess[2][2] && chess[0][0] == '*')
return -1;
return 0;
}
主函数
int main() {
int flag = 0;
while (1) {
manu();
scanf("%d", &flag);
switch (flag) {
case 1: game(); break;
case 2:return 0;
default:
printf("input error");
continue;
break;
}
}
}
void game() {
srand((unsigned int)time(NULL));
char chess[ROW][COL];
int flag = 0;
InitChess(chess, ROW, COL);
PrintBoard(chess, ROW, COL);
while (1) {
Player(chess, ROW, COL);
PrintBoard(chess, ROW, COL);
flag = judge(chess, ROW, COL);
if (flag == 1) {
printf("You win\n");
return;
}
else if(flag== -1){
printf("You lose\n");
return;
}
printf("电脑输入\n");
computer(chess, ROW, COL);
PrintBoard(chess, ROW, COL);
flag = judge(chess, ROW, COL);
if (flag == 1) {
printf("You win\n");
return;
}
else if (flag == -1) {
printf("You lose\n");
return;
}
}
