在另一个编译器中打印乱码的数组| C++
在另一个编译器中打印乱码的数组| C++
提问于 2019-04-21 22:25:10
我使用Visual Studio软件，一切工作正常。
当我在数组的输出以乱码的形式输出之后，我使用了另一个编译器。
我的代码：
print_board[9][9] = {};
print_board[0][0] = '\0';然后我将数据输入到数组中，它们会像这样打印：
?????·?²?
?|?-`???
???-?????
??|Z%??
?????????
·1²???
?????????
?????] @?
?????????这是打印的代码：
void Game::PrintWin(char print_board[][9]) {
for (int i = 0; i < 9; i++) {
for (int j = 0; j < 9; j++) {
cout << print_board[i][j];
}
cout << endl;
}
}这是我得到的唯一错误，但我不知道它是否与我的问题有关：
Game.cpp:5:23: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 [enabled by default]
print_board[9][9] = {};有没有人知道为什么会这样？
我不喜欢写太多代码，因为它会加载到论坛上，但下面是代码：
Game.cpp:
#include "Game.h"

board[5][5] = {};
print_board[9][9] = {};

tmp_input[0] = '\0';
print_board[0][0] = '\0';
board[5][5] = '\0';

你的问题是print_board[9][9] = {};和类似的，不要初始化你的2D数组。这是一个越界写入。
您的数组的有效索引是print_board[0][0]到print_board[8][8]，您的代码正在尝试访问超出数组末尾的print_board[9][9]。这也是一个单一的元素，而不是整个数组。
而不是像这样在构造函数中初始化成员变量：
Game::Game() : board{}, print_board{}, tmp_input{}, example{"PASS"}, quit{"QUIT"},play{}
