With this, we come to the end of this blog on ‘Linear Search in C’. The time complexity of a linear search is O(n). In the best-case scenario, the element is present at the beginning of the list and in the worst-case, it is present at the end. The time required to search an element using a linear search algorithm depends on the size of the list. If x does not match with any of the elements then return -1. If x matches with an element then return the index. A simple approach to implement a linear search isīegin with the leftmost element of arr and one by one compare x with each element. It checks each element of the list sequentially until a match is found or the whole list has been searched. We will be covering the following topics in this blog:Ī linear search, also known as a sequential search, is a method of finding an element within a list. In this blog on “Linear search in C”, we will implement a C Program that finds the position of an element in an array using a Linear Search Algorithm. Linear search is a very simple and basic search algorithm.
