Qbit编程学习笔记

考虑下面的一段代码#include <stdio.h>typedef struct{ int a[2]; double d;} struct_s;double fun(int i){ volatile struct_s s; s.d=3.14; s.a[i]=1073741824; printf("%f",s.d); return 0;}int main(){

#include "stdafx.h"#includeusing namespace std;class A {private:int val;public:A(int i) { val = i; }int value(int a) { return val + a; }};int main(){int(A::*pfun)(int);pf
