snake_test.c

#define _CRT_SECURE_NO_WARNINGS 1 #include "snake.h" void test() { int ret = 0; do { ret = 0; Snake snake = { 0 }; GameStart(&snake);//游戏开始前的初始化 GameRun(&snake);//玩游戏的过程 GameEnd(&snake);//游戏的善后 Sleep(800); system("cls");//清屏 setpos(40, 15); printf("要再来一次吗？？？（Y/N）"); ret=getchar(); getchar();//清理\n } while (ret=='Y'||ret=='y'); } int main() { //修该适合本地中文环境 setlocale(LC_ALL, ""); test();//贪吃蛇的测试 return 0; }

这是详细代码，之后会给大家详细解答。
