Explanation:

Searching for an element in an array entails going over the array and comparing each element with the specified target value.

Steps:

  1. Input the Array and Target Value:
    • Take the array and the element to search (target value) as input.
  2. Iterate Through the Array:
    • Start from the first element and check if it matches the target value.
  3. Check for Match:
    • If a match is found, print the index (or position) of the element and exit the search.
    • If the loop completes without finding the target, indicate that the element is not present in the array.
