至于iostream不能用，大概就是编译器缺文件，建议重装（
include <iostream> using namespace std;int main(int argc, char* argv[]){ cout << "Hello world!" << endl;return 0;}
重装解决90%问题。应该就是文件缺失。
1.没有保存或没有编译等诸如此类没有做准备工作的原因；2.如果不行，关掉Dev c++重来；3.如果实在不行，我也无能为力。我用Dev c++试了一下，在我这边用Dev c++可以编译与调试，也可以执行，可能是你那边出了些小问题，把电脑或Dev c++软件重启一下，应该就没问题了，问题不在于程序。
在Windows 环境中,我们运行 Dev-C++ 并在头文件写#include<bits/extc++.h>时,经常会收到[Error] iconv.h: No such file or directory的编译报错。 所以为了代替他,我们会写很多 #include<ext/pb_ds/hash_policy.hpp>#include<ext/pb_ds/assoc_container.hpp> ...
