C++,vs中pow和宏的使用

#include <iostream>using namespace std;//#define Mul  ++x*y++   //错的，必须要是Mul(x,y)#define Mul(x,y)  ++x*y++int main(){//cout<<pow(10,2);错误cout<<pow((float)10,2)<<endl;cout<<pow((double)10,2)<<endl;int a=2,b=4,c=8;int d =  Mul(a+b,b+c); //++2+4*4+8++ = 3+16+8 = 27 cout <<d<<endl;//27return 0;}
