你这代码里也没写加边框的程序呀。我给你写了一下,不过会闪烁,可以用句柄,如果没猜错的话你在学那个C语言游戏什么的哪本书吧?我也在学,这个是我以前写的,你可以参考下#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
int main(void)
{
int i, j;
int x = 1, y = 5;
int top = 1, bottom = 10, left = 1, right = 20; // 上下左右边界
int velocity_x = 1, velocity_y = 1; // 下落和移动距离量
while ( 1 )
{
x += velocity_x;
y += velocity_y;
system("cls"); // 清屏
/* 打印小球位置以上的边框 */
for ( i = top-1; i < x; i++ )
{
if ( i == top-1 )
{
for ( j = left-1; j <= right+1; j++)
printf("*");
printf("\n");
}
else
{
printf("*");
for ( j = left; j <= right; j++)
printf(" ");
printf("*\n");
}
}
/* 打印小球所在行小球前的边框 */
for ( i = left-1; i < y; i++ )
{
if ( i == left-1 )
printf("*");
else
printf(" ");
}
printf("o");
/* 打印小球所在行小球后的边框 */
for ( i += 1 ; i <= right+1; i++ )
{
if ( right+1 == i )
printf("*\n");
else
printf(" ");
}
/* 打印小球位置以下的边框 */
for ( i = x+1; i <= bottom+1; i++ )
{
if ( i == bottom+1 )
{
for ( j = left-1; j <= right+1; j++)
printf("*");
printf("\n");
}
else
{
printf("*");
for ( j = left; j <= right; j++)
printf(" ");
printf("*\n");
}
}
Sleep(50); // 等待50ms
/* 打到边界反向 */
if ( x == bottom || x == top )
{
printf("\a"); // 碰撞响铃
velocity_x = -velocity_x;
}
if ( y == right || y == left )
{
printf("\a");
velocity_y = -velocity_y;
}
}
return 0;
}
