关于代码的测试

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。
