二级C上机模拟试题及答案（6）

二级C上机模拟试题及答案（6） 2011： 函数ReadDat()实现从文件ENG.IN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PS6.OUT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。
