sizeof的相關用法

#include<iostream>
using namespace std;
class A
{
	static int b;

};
int  main()
{
 int a;
 short b;
 unsigned c;
 static int f;
 char d;
 cout<<sizeof(a)<<endl;
 cout<<sizeof(b)<<endl;
 cout<<sizeof(c)<<endl;
 cout<<sizeof(d)<<endl;
 cout<<sizeof(A)<<endl;
 cout<<sizeof(f)<<endl;
}

輸出爲：4,2，4,1,1,4.
