很奇怪的对象数组初始化现象：禁用拷贝构造后，用无参构造显示初始化类对象数组时，报错

Question

class test1{
public:
    test1(){
        cout << "default" << endl;
    }

    test1(const test1 &test) =delete;
    test1& operator=(const test1 &test) = delete;
};

int main() {
    test1 test[3] = {test1(), test1(), test1()};

	return 0;
}

报错：error: use of deleted function 'test1::test1(const test1&)'|

 

但test数组应该没有调用拷贝构造呀，证明如下

class test1{
public:
    test1(){
        cout << "default" << endl;
    }

    test1(const test1 &test){
        cout << "copy" << endl;
    }
    test1& operator=(const test1 &test){
        cout << "operator =" << endl;
        return *this;
    }
};

int main() {
    test1 test[3] = {test1(), test1(), test1()};



	return 0;
}

的输出为：

default
default
default

Process returned 0 (0x0)   execution time : 0.423 s
Press any key to continue.

刚刚又试了下  发现 不是数组初始化的问题，     只要是类似  test1 test = test1（）；这种用显示调用构造函数的都报上诉错wu

Answer 1

因为这两种方式都会调用复制构造函数，这是正常的
