关于Dev-C++4.9.9.0问题求教：

[huangliguo]

在Dev-C++4.9.9.0运行程序不通过：

#include<iostream.h>
void main()
{
cout<<"hello.\n";
cout<<"I am a student.\n";
}

错误信息：
1 d:\Dev-Cpp\include\c++\3.3.1\backward\iostream.h:31, from D:\Dev-Cpp\lizi\1.1.cpp In file included from d:/Dev-Cpp/include/c++/3.3.1/backward/iostream.h:31, from D:/Dev-Cpp/lizi/1.1.cpp

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 <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated.
3 D:\Dev-Cpp\lizi\1.1.cpp `main' must return `int'


这是为什么呢？
谁有Dev-C++4.9.9.0用法介绍吗

[renheihei]

#include <iostream>
using namespace std;
int main()
{
cout<<"hello.\n";
cout<<"I am a student.\n";
system("pause");
}

[insulator]

楼主要学一学标准c++
楼上的写得不错

[hcj2002]

呵呵

同意 renheihei(嘿嘿)

[ZKYcomputer]

在vc下可以啊

#include<iostream.h>
void main()
{
cout<<"hello.\n";
cout<<"I am a student.\n";
}

其实这样的代码是正确的，cout包含在iostream.h了，不过格式不被提倡而已。

你的问题是编译器的问题（没有设置好环境或者其他的问题···反之不是程序的问题）

[zhangfjj]

#include<iostream.h> 这是老标准的头文件写法

void main() 同样新标准要把main()定义的int型
dev-c++跟新标准比较紧，
所以才出现你这样的问题。
