内存中的各变量分配验证

#include <iostream>
using namespace std;

struct S
{
	int a;
	char b;
	int c;
	char d;
	char e;
	int f;
	double g;
	int h;
};
int main()
{
	S s;
	s.a = 10;
	s.b = 'b';
	s.c = 30;
	s.d = 'd';
	s.e = 'e';
	s.f = 60;
	s.g = 70.0;
	s.h = 80;

	cout<<sizeof(s)<<endl;

	void* x = &s;
	cout<<*(int*)x<<endl;	//a
	x = (int*)x+1;
	cout<<*(char*)x<<endl;  //b
	x = (int*)x+1;
	cout<<*(int*)x<<endl;	//c
	x = (int*)x+1;
	cout<<*(char*)x<<endl;	//d
	x = (char*)x+1;
	cout<<*(char*)x<<endl;	//e
	x = (char*)x+3;
	cout<<*(int*)x<<endl;	//f
	x = (int*)x+1;
	cout<<*(double*)x<<endl;	//g
	x = (double*)x+1;
	cout<<*(int*)x<<endl;	//h
	return 0;
}

输出结果为：
32
10
b
30
d
e
60
70
80
