内存单元中有一个ASCII码表.docx

1、内存单元中有一个ASCII码表编写程序，实现表的处理：内存单元中有一个ASCII码表，编写程序完成下面的功能： 首先输出表的内容； 插入一个数据，插入的数据和插入的位置从键盘输入； 对表中的数据进行排序，按升顺或降顺排序可以进行选择； 在表中查找某一个关键字，要查找的关键字从键盘输入；如果找到，输出查找的关键字并给出提示“find”,否则给出提示“no find”； 程序执行以后，输出表中的插入以后的内容和排序以后的内容； 程序有友好的运行界面；要求程序能够处理基本的错误信息；data segmenttable db20 4b 26 37 7c,0ah,0dh,$str db which da
