以下是一个简单的C++贪吃蛇游戏代码示例：
#include <iostream>#include <conio.h>#include <windows.h>using namespace std;bool gameOver;const int width = 20;const int height = 20;int x, y, fruitX, fruitY, score;int tailX[100], tailY[100];int nTail;enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };eDirection dir;void Setup(){ gameOver = false; dir = STOP; x = width / 2; y = height / 2; fruitX = rand() % width; fruitY = rand() % height; score = 0;}void Draw(){ system("cls"); for (int i = 0; i < width + 2; i++) cout << "#"; cout << endl; for (int i = 0; i < height; i++) { for (int j = 0; j < width; j++) { if (j == 0) cout << "#"; if (i == y && j == x) cout << "O"; else if (i == fruitY && j == fruitX) cout << "F"; else { bool print = false; for (int k = 0; k < nTail; k++) { if (tailX[k] == j && tailY[k] == i) { cout << "o"; print = true; } } if (!print) cout << " "; } if (j == width - 1) cout << "#"; } cout << endl; } for (int i = 0; i < width + 2; i++) cout << "#"; cout << endl; cout << "Score: " << score << endl;}void Input(){ if (_kbhit()) { switch (_getch()) { case 'a': dir = LEFT; break; case 'd': dir = RIGHT; break; case 'w': dir = UP; break; case 's': dir = DOWN; break; case 'x': gameOver = true; break; } }}void Logic(){ int prevX = tailX[0]; int prevY = tailY[0]; int prev2X, prev2Y; tailX[0] = x; tailY[0] = y; for (int i = 1; i < nTail; i++) { prev2X = tailX[i]; prev2Y = tailY[i]; tailX[i] = prevX; tailY[i] = prevY; prevX = prev2X; prevY = prev2Y; } switch (dir) { case LEFT: x--; break; case RIGHT: x++; break; case UP: y--; break; case DOWN: y++; break; default: break; } if (x >= width) x = 0; else if (x < 0) x = width - 1; if (y >= height) y = 0; else if (y < 0) y = height - 1; for (int i = 0; i < nTail; i++) { if (tailX[i] == x && tailY[i] == y) gameOver = true; } if (x == fruitX && y == fruitY) { score += 10; fruitX = rand() % width; fruitY = rand() % height; nTail++; }}int main(){ Setup(); while (!gameOver) { Draw(); Input(); Logic(); Sleep(10); } return 0;}请注意，这只是一个简单的贪吃蛇游戏代码示例，可能存在一些功能性的不足和bug。您可以根据需要进一步完善和优化代码。
