Question

一个简单的C++程序

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

刚学，编译器用的是：Dev-C++ .4.9的，但编译的时候出错，不知道原因何在？我漏了一些东西了吗？
对C++的学习很抓狂呀，不同的编译器对库的支持都不同，搞得我学习没什么热情。。。有点灰心了。。。
说明下错误原因，好不？？
1 D:\Program Files\DEV-CPP\include\c++\3.4.2\backward\iostream.h:31, from C:\Documents and Settings\Administrator\桌面\io.cpp In file included from D:/Program Files/DEV-CPP/include/c++/3.4.2/backward/iostream.h:31, from C:\Documents and Settings\Administrator\桌面\io.cpp

1 C:\Documents and Settings\Administrator\桌面\io.cpp from C:\Documents and Settings\Administrator\桌面\io.cpp

32:2 D:\Program Files\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.

4 C:\Documents and Settings\Administrator\桌面\io.cpp `main' must return `int'

就是这些了，看卡。

Answer 1

# include <iostream>
using namespace std;
int main(int argc,char *argv[])
{
cout << "I am a student";
return 0;
}

Answer 2

与编译器有关

Answer 3

# include <iostream>
using namespace std;
int main(int argc,char *argv[])
{
cout << "I am a student";
return 0;
}
建议用VC++编译环境

Answer 4

你把错误复制上来看看再说~
