二级C上机模拟试题及答案（6）

函数ReadDat()实现从文件中读取一篇英文文章存入到

字符串数组xx中; 请编制函数DelWord()分别按行删除空格、标点

符号以及10个不区分大小写的英文单词(you,for,your,on,no,if,

the,in,to,all), 余下的单词按顺序重新存入数组xx中, 最后调用

函数WriteDat()把结果xx输出到文件T中。

例如: 原文: You are a student.

结果: areastudent

原始数据文件存放的格式是:每行的宽度均小于80个字符, 含

标点符号和空格。

注意: 部分源程序存放在PROG1.C中。文章每行中的单词与单

词之间用空格或其它标点符号分隔, 每单词均小于20个字符。

请勿改动主函数main()、读数据函数ReadDat()和输出数据函

数WriteDat()的内容。
