To delete an element from the beginning of an array, you can use the following steps:

1. Declare a new array of the same type as the original array, with a length that is one less than the original array.
2. Use a loop to copy all elements of the original array, except the first element, to the new array.
3. Set the original array to the new array.

Here is an example in Java:

int[] arr = {1, 2, 3, 4, 5};
int[] newArr = new int[arr.length - 1];

for (int i = 0; i < newArr.length; i++) {
newArr[i] = arr[i + 1];
}

arr = newArr;
