Extern How?

全域吃透透寫法

a.h

extern double someVar;

a.cpp

#include
#include "a.h"
#include "c.h"
using namespace std;

int main() {
cout << someVar << endl;
test();
return 0;
}

b.cpp

#include "aaa.h"
double someVar = 1000;

c.h

void test();

c.cpp
#include
#include "aaa.h"

using namespace std;
#include "aaa.h"
void test() {
cout << someVar << endl;

}

就可以讓其他檔案也吃透透了，要非常小心這樣的用法，當程式數萬行之後，很容易把自己搞混。小心用。
