Answer 1

#include<iostream>
#include<windows.h>
#include<conio.h>
#include<time.h>
#include<string>
using namespace std;

int l,r;
char a[150][150],ch;
void HideCursor()
{
CONSOLE_CURSOR_INFO cursor_info = {1, 0};
SetConsoleCursorInfo(GetStdHandle(STD_OUTPUT_HANDLE), &cursor_info);
}
int main()
{
system("title 兄弟我尽力了."); //显示标题
HideCursor(); //隐藏光标
a[1][1]='a';
l=1;r=1;
cout<<l<<" "<<r<<endl;
for (int i=1;i<=10;i++)
{
for (int j=1;j<=10;j++)
cout<<a[i][j];cout<<endl;
}
while (1==1)
{
ch=_getch();
system("cls"); //刷新屏幕
a[l][r]=' ';
if (ch=='w'&&l-1>0) l--;
if (ch=='s'&&l+1<11) l++;
if (ch=='a'&&r-1>0) r--;
if (ch=='d'&&r+1<21) r++;
cout<<l<<" "<<r<<endl;
a[l][r]='a';
for (int i=1;i<=10;i++)
{
for (int j=1;j<=21;j++)
cout<<a[i][j];cout<<endl;
}

}
}
