Question

我正在做蛇游戏，基本上已经完成了；但是有时，当我运行它时，它首先会工作，然后清除（可能在我的代码中，它有很多清除）并返回错误代码-1073741571。
这是代码：

from bacher.models.User import User

编辑：大多数时候它都可以正常工作，只有有时候我会收到错误消息编辑：堆栈溢出在#include <iostream> #include <string> #include <stdio.h> #include <conio.h> #include "windows.h" #include <vector> #include <random> #include <ctime> #include <cmath> #include <windows.h> using namespace std; struct point { int x; int y; }; bool goTo(point p,vector<point>& snek) { bool flag=false; for (size_t i = 0; i < snek.size(); i++) { if (p.x == snek[i].x && p.y == snek[i].y) { return true; } } for (int i=snek.size()-1; i >0; i--) { snek[i] = snek[i - 1]; } snek[0] = p; return false; } void makeFood(point& apple, vector<point> snek) { bool appleValid = true; apple.x = (rand() % 19) + 1; apple.y = (rand() % 19) + 1; for (int i = 0; i < snek.size() - 1; i++) { if (apple.x == snek[i].x && apple.y == snek[i].y) { appleValid = false; break; } } if (!appleValid) { srand(time(NULL)); makeFood(apple,snek); } } int main() { vector<point> snek; snek.push_back({ 10,10 }); snek.push_back({ 10,9 }); snek.push_back({ 10,8 }); snek.push_back({ 10,7 }); int highscore= 0, score; bool tutorial = false; bool p = false; char move = 'w'; char sure = 'f'; string board[21][21]; int direction=2; point apple; apple.x = rand() % 20; apple.y = rand() % 20; for (int i = 0; i < 20; i++) { for (int j = 0; j < 20; j++) { board[i][j] = " "; } } bool loss = false; while (true) { score = snek.size() - 4; bool appleEaten = false; srand(time(NULL)); if (snek[0].x == 0 ) loss = true; if (snek[0].x == 20 ) loss = true; if (snek[0].y == 0 ) loss = true; if (snek[0].y == 20 ) loss = true; if (loss) { system("CLS"); if (score > highscore) { highscore = score; } cout << "You lost with a score of " << snek.size() - 4 << endl; cout << "Your highscore for this session is " << highscore<<endl; cout << "Press any key to play again" << endl; cout << "Press RMB to quit" << endl; while (true) { if (GetAsyncKeyState(VK_RBUTTON)) { system("CLS"); cout << "Are you sure you want to quit?

让我们仔细看看您的makeFood函数：

void makeFood(point& apple, vector<point> snek)
{
    bool appleValid = true;
    apple.x = (rand() % 19) + 1;
    apple.y = (rand() % 19) + 1;
    for (int i = 0; i < snek.size() - 1; i++)
    {
        if (apple.x == snek[i].x && apple.y == snek[i].y)
        {
            appleValid = false;
            break;
        }
    }
    if (!appleValid)
    {
        srand(time(NULL));
        makeFood(apple,snek);
    }

}

您的if语句可以使苹果处于蛇形位置时再次调用makeFood()，但是使用srand(time(NULL))可以将苹果放回原处，并再次调用该函数，然后再次无限次。删除srand(time(NULL))中的if(!appleValid)，您的程序就不会出现问题，因为您只需要随机种子即可。

如果可以的话，尝试将随机函数转换为<random>标头，但它也可以与rand一起使用：）
