关于宏函数的问题：运行的结果是125，125，1728，82；82是怎么来的
#include<iostream>using namespace std;
#define CUBE(a) ((a)*(a)*(a))
#define THREE(a) a*a*a
int main()
{
long x=5;
long y=CUBE(x);
long z=THREE(x);
cout<<"y:"<<y<<endl;
cout<<"z:"<<z<<endl;
long a=5,b=7;
y=CUBE(a+b);
z=THREE(a+b);
cout<<"y:"<<y<<endl;
cout<<"z:"<<z<<endl;
return 0;
}
