本文介绍了使用istringstream给出错误|为什么的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我有一个我创建的二进制文件。在其中,数据以二进制形式存储,但是我将以人类可读的形式显示它: [someOtherData] 6759A_block $ [ someOtherData] 我在temp_S中保存数据6759A_block $,声明为字符串。现在,我想要拆分第一个3字节远离temp_S,然后将其存储在unsigned int。要完成我的愿望,我写下面的代码段; unsigned int number; { string tmp(temp_S,0,3); istringstream temp_Istream(tmp); temp_Istream>>数;然而,当我编译我的小程序时,它给出一个错误如下所示;然而,当我编译我的小程序,它给出一个错误,如下所示:。} 错误:variable'std :: istringstream temp_S'具有初始化器但不完整类型 我的问题是: 编译器错误? 如何解决这个问题,并将前三个字节的数据转换为unsigned int? 编辑: 平台linux g ++ 解决方案 GCC指出错误当你忘记这一点: #include< sstream> // this is where istringstream is defined I have one binary file which I have created. In it, data is stored in binary form but I will show it in human readable form like ; [someOtherData]6759A_block$[someOtherData]I hold that data "6759A_block$" in temp_S, which is declared as string. Now, I want split first 3 byte away from temp_S, and then store it in unsigned int. To accomplish my wish, I have write below code segment; unsigned int number; { string tmp ( temp_S , 0 ,3 ); istringstream temp_Istream ( tmp ) ; temp_Istream >> number; }However, when I compile my small program, it gives an error shown below ;error: variable ‘std::istringstream temp_S’ has initializer but incomplete typeMy questions are :What is the meaning of this compiler error ?how can I fix that problem, and take first three byte of data to unsigned int ?EDIT :platform linuxg++ 解决方案 GCC gives that error when you forget this:#include <sstream> //this is where istringstream is defined 这篇关于使用istringstream给出错误|为什么的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
