# Binary Search in C2 min read

Binary search in C programming is to find an element’s position in a sorted Array. The following program for binary search finds the location of a searched element from the array.

Binary search is applied to sorted elements. So if the array is not sorted, you must sort it using a sorting technique. You can use any one of the sorting algorithms in c such as merge or bubble sort etc.

The search for the element that is to be searched and if found in an array, it will print its index number that the key is present.

## Binary Search Time Complexity:

• Best case:  O(1)
• Average case:  O(log n)
• Worst case:  O(log n)
