Question

我正在尝试在另一个对象中创建一个对象数组，并决定数组的大小。

当我尝试将“obj2T”分配给“obj2”时，为什么会出现错误？

在另一个对象中创建对象数组并确定数组大小的正确语法是什么？

#include <iostream>

using namespace std;

class classe2
{
    public:
        classe2();

    protected:

    private:
};

class classe1
{
    public:
        classe1(int value);
        void setClasse()
        {
        classe2 obj2T[grandezza];
        obj2=obj2T;
        }

    protected:

    private:
        const int grandezza;
        classe2 obj2[];
};

int main()
{
    cout << "Hello World!" << endl;
    return 0;
}

错误：

C:\cppProjects\project\main.cpp||In member function 'void classe1::setClasse()'
C:\cppProjects\project\main.cpp|22|error: incompatible types in assignment of 'classe2 [((classe1*)this)->classe1::grandezza]' to 'classe2 [0]'

正确的语法是

public static final String TABLE_NAME = "'Vehicle entry'";
public static final String COLUMN_REGISTRATION_NUMBER = "'Registration number'";
public static final String COLUMN_OWNER_NAME = "'Owner name'";
public static final String COLUMN_TYPE = "'Vehicle type'";
