In C++ programming, initializing an array within a constructor is a common practice, especially in object-oriented design. Consider a class named DataContainer that encapsulates an integer array. Our goal is to ensure this array is initialized appropriately when an object of the class is created....

Unlike in the case of specifyingclassname,createArraydoes not call the class constructor when you specify a fill value. The fill value is copied to each element of the array. Verify that the value ofprop1of each instance is7. [F.prop1] ...
After that, the Vector will fill itself with null values. We must consider that this method only helps us if we want to insert null values in our list. We can also transform the list to an ArrayList by using the constructor of the ArrayList class like in the previous examples or...
