【问题描述】:
我为大学作业编写了一个 C++ 程序。我使用在我的 Mac 上运行的 Netbeans 6.8 并且代码运行顺利,没有警告、错误或问题/错误。但是,当使用 CodeGear RAD Studio 2009 (C++ Builder) 在 Windows 计算机上编译和运行时,出现了几个错误。
[BCC32 Error] main.cpp(51): E2094 'operator<<' not implemented in type 'ostream' for arguments of type 'string'
[BCC32 Error] main.cpp(62): E2093 'operator==' not implemented in type 'string' for arguments of the same type
[BCC32 Error] main.cpp(67): E2093 'operator==' not implemented in type 'string' for arguments of the same type

[BCC32 Error] main.cpp(264): E2094 'operator>>' not implemented in type 'istream' for arguments of type 'string'
这些是正在使用的头文件
#include <iostream>
#include <fstream>
#include <cmath>
#include <stdio>
#include <windows> //I added this one just to check and still does not work (I didnt have it on Netbeans/Mac)
using namespace std;
任何想法是什么产生了错误,我该如何解决?

大胆猜测:你需要
#include <string>
