普通变量 在内存中栈式存储的证明

  #include<iostream>using namespace std;void main(){int a=1;int b=2;cout<<(int)&a<<endl;cout<<(int)&b<<endl;}

得出结果 a的地址大于b的

栈是向上生长的机从大到小

 

#include <iostream>using namespace std;class Aclass{public:int a;Aclass(int t){this->a=t;cout<<"constructor "<<a<<endl;}void inTest(){Aclass t21(21);Aclass t31(31);}~Aclass(){cout<<"destructor "<<a<<endl;}};void test(){Aclass t11(11);Aclass t12(12);}void main(){test();Aclass t1(1);Aclass t2(2);t2.inTest();}
