UC知道sizeof求函数大小

#include "stdafx.h"
#include <iostream>
#include "Student.h"
using namespace std;
void func(Student &b)
{
b.display();
b.change(101,80.5);
b.display();
}
int main()
{
Student stud(101,78.5);
func(stud);
cout << sizeof(Student) << endl << sizeof(stud) << endl;
return 0;
}
我想知道func 函数的大小 应该怎么写sizeof?

看看文档中的说明吧：不可操作对象
The sizeof operator cannot be used with the following operands:
Functions. (However, sizeof can be applied to pointers to functions.)
Bit fields.
Undefined classes.
The type void.
Dynamically allocated arrays.
External arrays.
Incomplete types.
Parenthesized names of incomplete types
