错误'operator =' function is unavailable in 'A'

[boycott2]

// testCreate.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
class A
{
public:
A():i(2)
{

printf("A is create\n");
}

~A()
{
printf("A is destroyed\n");
}

const int i;
};

A& createA(A &a)
{
A b;
return b;
}

int main(int argc, _TCHAR* argv[])
{

A a;
a=createA(a);

return 0;
}

编译总是报错：error C2582: 'operator =' function is unavailable in 'A'
请大家看看什么原因

恩，有const成员默认的operator =也不行。谢谢phisher

[phisherr]

没有operator =函数，
再说有const成员默认的operator =也不行；
所以你还是 createA(A &a) 返回指针把

[phisherr]

当然，要返回堆上的指针
