Question

how to display all array elements

Answer 1

For example:

for(int i=0; i<arrSize; i++){
cout << a[i] << ' ';
}

Answer 2

It must be done by using a loop.

A two-dimensional array requires nested loops.

Answer 3

So as written before, you have to use a for loop and nested loops if it is a multiple dimensional array. Compared to C, if you just write :
cout << array ;
You don’t get all elements of the array, but the memory adress and particulary the adress of the first element ( array[0] ).
