用DEV-C++编译是总是有警告:
32:2 C:\Dev-Cpp\include\c++\3.4.2\backward\backward_warning.h #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <iostream> instead of the deprecated header <iostream.h>. To disable this warning use -Wno-deprecated. V-C++,

那么你应该这样(新标准)如下:

#include <iostream> //C++头文件,去掉.h
#include <fstream>
#include <cstdlib> //C头文件,在原有文件名前加c,并去掉.h
using namespace std; //包括std名字空间

int main() //main函数必须返回int型,不再支持void
{
ofstream fout("output.dat", ios_base::binary);
//在文件操作中使用ios_base类代替早期的ios类
return 0; //这一条语句何以省略
