What is Binary Search in C?

Binary search is a search algorithm. It is used for searching an element in a sorted array. It works by repeatedly dividing the search interval in half until the element is found or the interval is empty.

Scope of Binary Search in C?

Binary search works by repeatedly dividing the search interval in half until the desired element is found or the search interval is empty. To perform a binary search in C, the array must be sorted in ascending order.

Algorithm for Binary Search in C

Binary search is a search algorithm that  is used to find out the position of a target value within a sorted array. It operates by continually halving the search interval.
The algorithm compares the target value to the value of the array’s middle element. If they are not equal, the half in which the target cannot lie is eliminated and the search continues either in the lower half or in the upper half, until the target value is found.

Binary Search vs Linear Search

Binary Search Linear Search
(i) Binary search works by repeatedly dividing the search interval in half until the element is found. (i) Linear search is a basic search algorithm that looks through a list of items one by one, in order, until it finds the desired item.
(ii) It is complicated and an efficient search algorithm with a time complexity. (ii) It is simpler and easy to implement than binary search.
(iii) It is faster search algorithm than linear search. (iii) It is slower.
(iv) This makes binary search much more efficient (fast) than linear search, which must check each item individually. (iv) It is the most basic search algorithm and can be used when the data isn’t sorted.
