[英]Need assistance with a for loop in Tic Tac Toe game
我的程序没有迭代就退出了。 它会自动转到“你是谁”。 没有冠军功能,程序运行正常。 它可能是一些明显的错误我失踪了。 如果有人愿意,我会非常感激。
#include <iostream>
#include <string>
#define GRID_SIZE 3
class TicTacToe {
private:
char map[GRID_SIZE][GRID_SIZE];
public:
void champion() {
const char *possiblities[8]{
"123"
"456"
"789"
"147"
"159"
"258"
"369"
"753"
};
for (int i = 0; i < 8; i++) {
bool winner = true;
char previous_pos = '0';
const char *possible_moves = possiblities[i];
for (int index = 0; index < GRID_SIZE; index++) {
char character = possible_moves[i];
int entered_num = character - '0';
int grid_space = entered_num - 1;
int row = index / GRID_SIZE;
int col = index % GRID_SIZE;
char grid_coordinate = map[row][col];
if (previous_pos == '0') {
previous_pos = grid_coordinate;
} else if
(previous_pos == grid_coordinate) {
continue;
} else {
winner = false;
break;
}
}
if (winner = true) {
std::cout << "YOU WON" << std::endl;
exit(0);
break;
}
}
}
void playgame() {
std::string input;
while (true) {
std::cout << "Go player one" << std::endl;
getline(std::cin, input);
if (input != " ") {
char entered = input.c_str()[0];
if (entered >= '1' && entered <= '9') {
int entered_num = entered - '0';
int index = entered_num - 1;
int row = index / 3;
int col = index % 3;
char grid_position = map[row][col];
if (grid_position == 'X' || grid_position == 'O') {
std::cout << "Space taken. Try again" << std::endl;
} else {
map[row][col] = (char) 'X';
break;
}
} else {
std::cout << "Only numbers 1 - 9" << std::endl;
}
} else {
std::cout << "Have to enter something, try again" << std::endl;
}
}
}
void generateGrid() {
int number = 1;
for (int x = 0; x < GRID_SIZE; x++) {
for (int y = 0; y < GRID_SIZE; y++) {
map[x][y] = std::to_string(number).c_str()[0];
number += 1;
}
}
}
void tictacToeMap() {
std::cout << std::endl;
for (int x = 0; x < GRID_SIZE; x++) {
for (int y = 0; y < GRID_SIZE; y++) {
std::printf(" %c ", map[x][y]);
}
std::cout << std::endl;
}
}
TicTacToe() {
generateGrid();
while (true) {
tictacToeMap();
playgame();
champion();
}
}
};
int main() {
TicTacToe tic;
tic.playgame();
return 0;
}
问题出在这里:
if (winner = true) {
std::cout << "YOU WON" << std::endl;
exit(0);
break;
}
你可能意味着:
if (winner == true) {
std::cout << "YOU WON" << std::endl;
exit(0);
break;
}
首先,做Max Meijer所说的,用if(winner == true)
替换if(winner = true)
if(winner == true)
。 但该计划仍然被打破。 问题是在你的字符串数组中,你没有用逗号分隔每个字符串,所以当我的调试器访问const char *possible_moves
,它最终只是将整个数组连接在一起。 所以只需用逗号分隔可能性数组中的每个字符串,如下所示:
const char *possiblities[8]{
"123",
"456",
"789",
"147",
"159",
"258",
"369",
"753"
};
