c写贪吃蛇代码及讲解

C写贪吃蛇代码的方法如下：

首先，我们需要定义蛇的结构体及其属性。蛇的结构体可以包括蛇头坐标，蛇身长度，蛇身坐标列表，以及蛇移动的方向等属性。

接着，我们需要定义游戏界面，并初始化蛇的方向、蛇身的初始长度和坐标。

在游戏循环中，我们需要监听玩家的输入，根据输入改变蛇移动的方向。同时，我们需要根据蛇的方向更新蛇头的坐标，并将其加入到蛇身的坐标列表中。

在最后，我们需要判断蛇是否吃到了食物。如果蛇头的坐标与食物坐标相同，则蛇身长度加1，食物重新生成，并将其坐标加入到蛇身坐标列表中。

在循环中，我们还需要判断蛇是否撞墙或者咬到自己。如果蛇头坐标超出了游戏界面边界，或者与蛇身的其他坐标相同，则游戏结束。

最后，在游戏循环结束后，我们需要释放资源，并显示玩家的得分。

这是一个简单的贪吃蛇游戏代码的框架。通过不断完善和优化，可以实现更加实用和有趣的贪吃蛇游戏。

帮我用C语言写贪吃蛇代码

好的，我可以为您提供贪吃蛇的代码。以下是一个简单的贪吃蛇游戏的C源代码：

#include <stdio.h>
#include <conio.h>
#include <windows.h>

#define ROWS 20
#define COLS 20

void gotoxy(int x, int y) {
    COORD coord = { x, y };
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

void drawBorder() {
    int i, j;
    for (i = 0; i < ROWS + 1; ++i) {
        for (j = 0; j < COLS + 1; ++j) {
            if (i == 0 || i == ROWS || j == 0 || j == COLS) {
                gotoxy(i, j);
                printf("+");
            }
        }
    }
}

int main() {
    int headX, headY;
    char input;
    int gameOver = 0;
    int score = 0;
    int tailX[100];
    int tailY[100];
    int tailLen = 0;

    headX = ROWS / 2;
    headY = COLS / 2;

    while (1) {
        gotoxy(0, 0);
        printf("Score: %d\n", score);
        drawBorder();

        // Draw the snake's head
        gotoxy(headX, headY);
        printf("O");

        // Record the previous position of the snake's head
        tailX[tailLen] = headX;
        tailY[tailLen] = headY;
        tailLen++;

        // Clear the last position of the snake's tail.
        gotoxy(tailX[0], tailY[0]);
        printf(" ");
        tailLen--;
        int i;
        for (i = 0; i < tailLen; ++i) {
            tailX[i] = tailX[i + 1];
            tailY[i] = tailY[i + 1];
        }

        if (_kbhit()) {
            input = _getch();
            if (input == 'w') {

            else if (input == 'a') {
                headY--;
            }
            else if (input == 's') {
                headX++;
            }
            else if (input == 'd') {
                headY++;
            }
        }

        if (headX == 0 || headX == ROWS || headY == 0 || headY == COLS) {
            gameOver = 1;
        }

        // Check if the snake's head intersects with its tail
        for (i = 0; i < tailLen; ++i) {
            if (headX == tailX[i] && headY == tailY[i]) {
                gameOver = 1;
                break;
            }
        }

        if (gameOver) {
            gotoxy(ROWS / 2 - 3, COLS / 2);
            printf("Game Over");
            break;
        }

        Sleep(100);
    }

    return 0;
}

这是一个基础的代码，您可以根据您的需求进行修改。
