我的想法和6#相同

#include<stdio.h>
#include <conio.h>
int main()
{
    int x=0,y=0,offset[4][2]={0,1,1,0,0,-1,-1,0},direction=0,order;
    char dir_name[4][6]={"Up","Right","Down","Left"};
    printf("****************************************************\n");
    printf("**               Robot Move                       **\n");
    printf("**                                                **\n");
    printf("**             Input Your Order                   **\n");
    printf("**               -1 Turn Left                     **\n");
    printf("**               -2 Turn Right                    **\n");
    printf("**              n>0 Move Forward n step(s)        **\n");
    printf("**                0 Exit                          **\n");
    printf("****************************************************\n");
    printf("Now Position:  X:%d,Y:%d   Direction:%s\n",x,y,*(dir_name+direction));
    do
    {
        scanf("%d",&order);
        if(order == -1)
            direction = (direction + 3) % 4;
        if(order == -2)
            direction = (direction + 1) % 4;
        if(order > 0)
        {
            x += offset[direction][0] * order;
            y += offset[direction][1] * order;
        }
        printf("Now Position:  X:%d,Y:%d   Direction:%s\n",x,y,*(dir_name+direction));
    }while(order != 0);
    printf("Robot Stop!!\nFinal Position:  X:%d,Y:%d   Direction:%s\n",x,y,*(dir_name+direction));
    printf("Press Any Key to Exit");
    getch();
    return 0;
}

从BFS(Breadth First Study)到DFS(Depth First Study)

//用一个angle变量表示转过的角度，对4取余 #include <stdio.h> int main() { int x=0; int y=0; int command=0; int angle=0; //angle表示转过的角度是90的angle倍 while (scanf_s("%d",&command)!=0) { if (command==0) { break; } else { switch(command) { case -2: angle+=3; break; case -1: angle++; break; default: switch(angle%4) { case 0: x+=command; break; case 1: y+=command; break; case 2: x-=command; break; case 3: y-=command; break; default: break; } break; } } } printf("%d %d\n",x,y); return 0; }
