Question

我正在开发一个tic tac toe游戏，需要创建一个根据用户输入创建棋盘的功能。可以是3x3或更大我到目前为止有这个，但是当我运行时打印内存位置。

#include <iostream>
#include <stdlib.h>
#include <time.h>

using namespace std;

// Array which creates boeard based on user input
int *drawboard(int width, int height)
{
int* board_data = new int[width * height];
int** board = new int* [width];
for (int i = 0; i < width; ++i) 
{
    board[i] = board_data + height * i;
}
return board_data;
}






void main()
{

int width = 0;
int height = 0;


cout << " Welcome to Tic Tac Toe v1! " << endl;
cout << " Choose your board size, enter width: " << endl;
cin >> width;
cout << " Choose your height: " << endl;
cin >> height;
cout << drawboard << endl;
int *board = drawboard(width, height);
delete[] board;



system("pause");

}

Answer 1

我认为this post会帮助你很多。看来你只是试图声明一个动态的2D整数数组，然后使用虚拟2D数组作为tic tac toe board，对吗？不完全确定drawboard()的含义，但这是一种打印网格的简单方法：

void printGrid(int y, int x) {
    for (int j = 0; j < y; j++) {
        for (int i = 0; i < x; i++) cout << " ---";
        cout << endl;
        for (int i = 0; i < x; i++) cout << "|   ";
        cout << "|" << endl;
    }
    for (int i = 0; i < x; i++) cout << " ---";
    cout << endl;
}

这是我的代码，当我运行它我的输出是 AAA BBB CCC 如果我输入3x3板

#include <iostream>
#include <stdlib.h>
#include <time.h>
#include <iomanip>

using namespace std;

// Array which creates boeard based on user input
char **createboard(int rows, int cols)
{
char** boardArray = new char*[rows];
for (int i = 0; i < rows; ++i) {
    boardArray[i] = new char[cols];
}

// Fill the array
for (int i = 0; i < rows; ++i) {
    for (int j = 0; j < cols; ++j) {
        boardArray[i][j] = char(i + 65);
    }
}

// Output the array
for (int i = 0; i < rows; ++i) {
    for (int j = 0; j < cols; ++j) {
        cout << boardArray[i][j];
    }
    cout << endl;
}

// Deallocate memory by deleting
for (int i = 0; i < rows; ++i) {
    delete[] boardArray[i];
}
delete[] boardArray;
return boardArray;
 }



 int main()
 {

int rows = 0;
int cols = 0;
char **boardArray = createboard(rows, cols);
cout << " Welcome to Tic Tac Toe v1! " << endl;
cout << " Choose your board width: " << endl;
cin >> rows;
cout << " Choose your board height " << endl;
cin >> cols;
cout << endl;
createboard(rows, cols);






system("pause");

}
