int main()
{
cout<<"AREA(R)="<<AREA(3)<<endl;
cout<<"Area(r)="<<Area(3)<<endl;
int height=100;
cout<<"CUBE(X)="<<CUBE(height++)<<endl;
cout<<"height="<<height<<endl;
height=10;
cout<<"Cube(s)="<<Cube(height++)<<endl;
cout<<"height="<<height<<endl;
return 0;
}
為什么上述代碼height兩次輸出不一樣;
第一次height輸出為103,第二次為11
