C++函数参数中的： 值传递，地址传递，双向传递

#include"iostream"using namespace std;const int N = 8;int main(){void s(int &a, int &b);int i = 3, b = 5;s(i, b);system("pause");return 0;}void s(int &a, int &b){int temp;temp = a;a = b;b = temp;}

引用： 双向传递！

#include"iostream"using namespace std;const int N = 8;int main(){void s(int *a, int *b);int i = 3, b = 5;s(&i, &b);system("pause");return 0;}void s(int *a, int *b){int temp;temp = *a;*a = *b;*b = temp;}

地址传递。     注意： 存储空间的区别。

#include"iostream"using namespace std;const int N = 8;int main(){void s(int a, int b);int i = 3, b = 5;s(i, b);system("pause");return 0;}void s(int a, int b){int temp;temp = a;a =b;b= temp;}

值传递：          达不到双向传递的目的；
