自考新教材-p180

源程序：

//基类与子类占用空间及字节对齐
#include<iostream>
using namespace std;

class BaseClass
{
int v1,v2;
char v4;
public:
int temp1(){}
};

class DerivedClass:public BaseClass
{
int v3;
int *p;
public:
int temp(){}
};

int main()
{
cout<<"Base="<<sizeof(BaseClass)<<endl;
cout<<"Derived="<<sizeof(DerivedClass)<<endl;
return 0;
}

//在32位系统中，指针的大小是4字节，而不是8字节

运行结果：
