用C语言实现这行C++代码 pathStack.push(new int[2]{cury, curx});

在C语言中，我们可以使用结构体代替动态内存分配来完成这个操作。下面是一个示例代码：

struct int_arr {
    int arr[2];
};

struct int_arr* create_int_arr(int a, int b) {
    struct int_arr* new_int_arr = malloc(sizeof(struct int_arr));
    new_int_arr->arr[0] = a;
    new_int_arr->arr[1] = b;
    return new_int_arr;
}

struct int_arr* arr = create_int_arr(cury, curx);
pathStack.push(arr);

首先，我们定义了一个名为 `int_arr` 的结构体，它包含一个大小为 2 的整型数组。然后，我们实现了一个名为 `create_int_arr` 的函数，该函数接受两个整数作为参数，并返回指向新分配的 `int_arr` 结构体的指针。该函数通过 `malloc()` 函数为结构体分配内存，并将输入参数存储在数组中。最后，我们创建了一个指向新分配的 `int_arr` 结构体的指针，并将其作为参数传递给 `pathStack.push()` 函数。

c++实现俄罗斯方块小游戏

罗斯方块是一款经典的游戏，它的实现可以使用C++语言。游戏的实现需要用到图形界面库和计时器等功能。游戏的主要逻辑是方块的移动和旋转，以及方块与地图的碰撞检测。下面是一个简单的俄罗斯方块游戏实现的代码框架：

#include <iostream>
#include <windows.h>
#include <conio.h>
#include <time.h>

using namespace std;

const int WIDTH = 10; // 地图宽度
const int HEIGHT = 20; // 地图高度
const int BLOCK_SIZE = 4; // 方块大小

int map[HEIGHT][WIDTH]; // 地图数组
int block[BLOCK_SIZE][BLOCK_SIZE]; // 方块数组

int curX, curY; // 当前方块的位置
int curBlock; // 当前方块的形状
int nextBlock; // 下一个方块的形状

int score; // 得分
int level; // 等级

// 初始化游戏
void initGame();

// 绘制游戏界面
void drawGame();

// 生成新的方块
void newBlock();

// 方块下落
void blockDown();

// 方块左移
void blockLeft();

// 方块右移
void blockRight();

// 方块旋转
void blockRotate();

// 消除满行
void clearLine();

// 判断游戏是否结束
bool isGameOver();

// 主函数
int main() {
    initGame();
    while (true) {
        drawGame();
        blockDown();
        if (isGameOver()) {
            break;
        }
    }
    return 0;
}

其中，initGame()函数用于初始化游戏数据，drawGame()函数用于绘制游戏界面，newBlock()函数用于生成新的方块，blockDown()函数用于方块下落，blockLeft()和blockRight()函数用于方块左右移动，blockRotate()函数用于方块旋转，clearLine()函数用于消除满行，isGameOver()函数用于判断游戏是否结束。
