学习C++ primer plus第九章的两个文件链接的问题

[nnh]

程序清单9.6:

// twofile1.cpp -- variables with external and internal linkage
#include <iostream> // to be compiled with two file2.cpp
int tom = 3; // external variable definition
int dick = 30; // external variable definition
static int harry = 300; // static, internal linkage

// function prototype
void remote_access();

int main()
{
using namespace std;
cout << "main() reports the following addresses:\n";
cout << &tom << " = &tom, " << &dick << " = &dick, ";
cout << &harry << " = &harry\n";
remote_access();
system("pause");
return 0;
}


程序清单9.7:

// twofile2.cpp -- variables with internal and external linkage
#include <iostream>
extern int tom; // tom defined elsewhere
static int dick = 10; // overrides external dick
int harry = 200; // external variable definition,
// no conflict with twofile1 harry

void remote_access()
{
using namespace std;
cout << "remote_access() reports the following addresses:\n";
cout << &tom << " = &tom, " << &dick << " = &dick, ";
cout << &harry << " = &harry\n";
}

书上说要对这两个文件进行链接才可调试．我用的是Dev-C++调试器，不会做呀？谢大家帮忙．

放在一个工程编译就可以了吧。
或者
g++ twofile1.cpp twofile2.cpp

那需要用什么软件呢？我只安装了Dev-C++呀．

楼主最好到linux下面去试验，或者安装一个mingw（这个是windows版本的gcc）。
然后分别将两个源文件（twofile1.cpp和twofile2.cpp）编译为两个目标文件（obj文件），然后用连接器ld将两个目标文件链接成为一个可执行文件。
