使用递归方法的反向ifstream输入 、 我有一个函数int Reverse(ifstream&inFile,int level)。它应该一次读取一个字符,直到到达特定的分隔符。然后该函数以相反的顺序显示这些字符。分隔符被返回给调用函数。分隔符不反转。|| someValue == EOF);{ int input = inFile.get();checkSeparator(inp ...

ifstream 是 char 类型的 basic_ifstream 模板的特化。根据您的需要,比如读取UTF-16编码文件,您可能必须使用不同的专业化( wifstream )或甚至使用特殊的区域设置(阅读此内容以了解有关区域设置的更多信息)。 是ifstream infile(“test.txt”,ifstream :: in | ifstream :: binary); 正确的语法使用多个 标志? 是...
