函数ReadDat( )实现从文件IN.DAT中读取一篇英文文章存入到字符串数组xx中；请编制函数StrOR( )，其函数的功能是：以行为单位依次把字符串中所有小写字母o左边的字符串内容移到该串的右边存放，然后把小写字母o删除，余下的字符串内容移到已处理字符串的左边存放，之后把已处理的字符串仍按行重新存入字符串数组xx中。最后main()函数调用函数WriteDat()把结果xx输出到文件OUT5.DAT中。-Function ReadDat () implementation from the file IN.DAT read an article in English in the deposit to the string array xx　Prepare function StrOR (), its function is the function: to act in turn to a string of all units in lowercase letters o the left of the string to move the contents of the right of the string storage, and then lowercase o remove the remaining contents of the string the string to move the left processed stored, and then the line has been re-processed into character strings based upon the xx in the string array. Finally main () function call function WriteDat () output the results to a file OUT5.DAT in xx.
