这是源程序，不完整，但是可以运行

奇怪的是每次运行提示输入后，输入Initialize position，执行的结果都不一样。按照我的想法是每次闪烁到最后都应该是0才对。请高手看看，能不能指导指导什么地方的问题，小弟不胜感激。

还有就是C的转义字符里面有没有哪个是直接回到上一行的？就是说光标本来在第六行，有什么转义字符能让他回到第五行？

首先谢谢二楼，握着这系统不能include windows.h，画图也画不了哦。 我想知道的是我的程序哪个地方是有问题的。

[赵4老师]

In the following list of ANSI escape sequences, the abbreviation ESC represents the ASCII escape character 27 (1Bh), which appears at the beginning of each escape sequence. ESC[PL;PcH Cursor Position: Moves the cursor to the specified position (coordinates). If you do not specify a position, the cursor moves to the home position--the upper-left corner of the screen (line 0, column 0). This escape sequence works the same way as the following Cursor Position escape sequence. ESC[PL;Pcf Cursor Position: Works the same way as the preceding Cursor Position escape sequence. ESC[PnA Cursor Up: Moves the cursor up by the specified number of lines without changing columns. If the cursor is already on the top line, ANSI.SYS ignores this sequence. ESC[PnB Cursor Down: Moves the cursor down by the specified number of lines without changing columns. If the cursor is already on the bottom line, ANSI.SYS ignores this sequence. ESC[PnC Cursor Forward: Moves the cursor forward by the specified number of columns without changing lines. If the cursor is already in the rightmost column, ANSI.SYS ignores this sequence. ESC[PnD Cursor Backward: Moves the cursor back by the specified number of columns without changing lines. If the cursor is already in the leftmost column, ANSI.SYS ignores this sequence. ESC[s Save Cursor Position: Saves the current cursor position. You can move the cursor to the saved cursor position by using the Restore Cursor Position sequence. ESC[u Restore Cursor Position: Returns the cursor to the position stored by the Save Cursor Position sequence. ESC[2J Erase Display: Clears the screen and moves the cursor to the home position (line 0, column 0). ESC[K Erase Line: Clears all characters from the cursor position to the end of the line (including the character at the cursor position).

需要在CONFIG.SYS中添加一行 DEVICE=ANSI.SYS 并重启DOS

[陌上_桑]

我用的是Win7 32位 编译器是Turbo C 3.0

有没有人啊，来看看啊，多谢指导啊。谢谢啦。

[陌上_桑]

都没有人看看吗？

标准库提供的都是流式IO，做不到你想要的效果。 估计你想要的效果要么用GUI，要么用终端IO这样的API才能解决。 代码太长，没有重点，懒得看了。
