贪吃蛇
???算是对大一课设的交代>>>,代码抄过来的
vs2020下编译,仅使用Sleep()和system(“cls”),_kbhit(),等几个win api
结构: —— main.c global.c global.h
主要思路:2维数组每个点分别存墙(1),空地(0),蛇身体(2),食物点(3).然后遍历2维数组printf绘图
蛇身体长度通过int* body[]指针数组指向对应地图点,
main.c
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

#include "global.h"
extern int overFlag;
int main(int argc,char *argv[]) { while (1) { printf("输入y修改设置(否则按下任意键: "); fflush(stdout); if (_getch() == 'y') { GetSet(); } StartGame(); printf("Game Over!!!\n 按下任意键结束 \n"); _getch(); overFlag = 1; system("cls"); } return 0; }
