To search for a specific element in an unsorted array, you can use a linear search algorithm. This involves looping through each element of the array and comparing it to the element you are searching for. If a match is found, the search is complete and the index of the element is returned. If no match is found, the search continues until all elements have been checked, at which point the element is not found in the array and a message to that effect is returned.

To insert an element into an unsorted array, you can simply add the element to the end of the array, provided there is sufficient space. If the array is already full, you will need to create a new, larger array and copy all the elements from the original array into the new one.

To delete an element from an unsorted array, you can simply remove it by shifting all the elements after it one position to the left. This will leave a gap at the end of the array, which you can fill by reducing the size of the array or by shifting all the remaining elements to the left to fill the gap.
