Which of the following is the correct way to initialize all the elements of array with 0?

In C++, you can initialize all elements of an array to 0 in the following way:

int array[5] = {0};

In this case, the array named 'array' has 5 elements, all of which are initialized to 0.

In Python, you can do it like this:

array = [0]*5

In this case, the list named 'array' has 5 elements, all of which are initialized to 0.

In Java, you can do it like this:

int[] array = new int[5];

In Java, when you create an array of primitive types, it is automatically initialized to the default value for the type, which is 0 for integers.

In JavaScript, you can do it like this:

let array = new Array(5).fill(0);

In this case, the array named 'array' has 5 elements, all of which are initialized to 0.
