How do you add elements to an array in C++?

Approach:

1. First get the element to be inserted, say x.
2. Then get the position at which this element is to be inserted, say pos.
3. Then shift the array elements from this position to one position forward, and do this for all the other elements next to pos.
4. Insert the element x now at the position pos, as this is now empty.

How do you add two arrays?

concat(array1, array2) to merge 2 or more arrays. These approaches are immutable because the merge result is stored in a new array. If you’d like to perform a mutable merge, i.e. merge into an array without creating a new one, then you can use array1.

How do you add elements to an empty array in C++?

Can you add two arrays in Java?

You cannot use the plus operator to add two arrays in Java e.g. if you have two int arrays a1 and a2, doing a3 = a1 + a2 will give a compile-time error. The only way to add two arrays in Java is to iterate over them and add individual elements and store them into a new array.
