简易文本编辑器数据结构课程设计

这是tongji university online judge的一道题，现在这个题库已经没有了，我把原题贴出来，你就知道这个程序什么意思了Problem一个简单的行编辑程序的功能是：接受用户从终端输入的程序或数据，并存入用户的数据区。由于用户在终端上进行输入时，不能保证不出差错，因此，若在编辑程序中，“每接受一个字符即存入用户数据区”的做法显然不是最恰当的。较好的做法是，设立一个输入缓冲区，用以接受用户输入的一行字符，然后逐行存入用户数据区。允许用户输入出差错，并在发现有误时可以及时更正。例如，当用户发现刚刚键入的一个字符是错的时，可补进一个退格符"#"，以表示前一个字符无效；如果发现当前键入的行内差错较多或难以补救，则可以键入一个退行符"@"，以表示当前行中的字符均无效。如果已经在行首继续输入'#'符号无效。 Input输入一个多行的字符序列。但行字符总数（包含退格符和退行符）不大于250。 Output按照上述说明得到的输出。 Sample Inputwhli##ilr#e(s#*s) outcha@putchar(*s=#++);Sample Outputwhile(*s)putchar(*s++);
