我写了3个文件，一个类声明，一个写类的接口，还有一个使用类的程序，为什么
编译借口文件的时候总提示 [Linker error] undefined reference to `WinMain@16'
ld returned 1 exit status

谢谢啦

are you writing a GUI program or a console program?

Console program does not call WinMain(), it calls main().

就是在devc++里面打开source文件然后写的啊，不理解你说的那2个术语。。。

If that happens, try the following (without using any IDE).
The baisc idea is still:

edit sourc code --> compile --> link --> run

Step 1: edit source code

prepare 3 files as follows (using any text editor):

class.h

class A
{
public:
    A(int i_=0);
    void print() const;
private:
    int i;
};

class.cpp

#include \"class.h\"
#include <iostream>

A::A(int i_) : i(i_)
{
}
void A::print() const
{
    std::cout<<i<<std::endl;
}

main.cpp

#include <iostream>
#include \"class.h\"
using namespace std;


int main()
{
    A a(3);
    a.print();
    return 0;
}

Step 2: compile and link

Open a command prompt window, and run

C:\Dev-Cpp\bin\g++ main.cpp class.cpp

Step 3: run

run a.exe

不好意思，第2步里面输入的命令和自己文件存放的位置有关吗？麻烦能说清楚些不，我是新手，好多不明白的

问题解决啦，太谢谢了！关于这方面的东西有教材之类的吗？

Are you self-learning programming?

If you have a teacher, he should have taught you this "climb" step before the "walk" step (using IDE).

我是一个人课余时间在学的，有什么好的方法吗
