Like in Java, there’s a way to set null values in array elements,

Integer[] arr = new Integer[5];

In here, arr is an Integer array with size 5 contains null by default

So can we do the same in C++?

>Solution :

In Java, Integer is an object type, not a primitive type, so it’s allowable to to set one to null. C++ doesn’t have equivalent object types. A better analogue would be the following java:

int[] arr = new int[5];

Here you have a primitive int type which can’t be set to a null value. In C++ it’s the same thing.

The closest you can do is set all values to 0 or some other sentinel value. Either that or create your own Integer type which I wouldn’t advise.
