Introduction to C + + Classic-Example 7.9-Array of objects, batch production

1: In the contents of the array we learned that the array is a specified amount of content allocated by the pointer. Similarly, an array can contain objects. The Declaration object array is in the following form:

Box Boxarray[5];

Box Boxarray2[2]={box (1,1,1), Box (2,2,2)};

Box Boxarray3[3]={3,stylebox};

It is worth noting that the first method of applying an array of objects must ensure that the class contains the default good enough function, or the compiler will error. Similarly, you can request a dynamic array from an object pointer. For example:

box* box;

Pbox=new box[n];//n as an integer

You also need to confirm that the box contains a default constructor.
