C Program to implement Binary search. Binary search technique is simple searching technique which can be applied if the items to be compared are either in ascending order or descending order. The general idea used in binary search is similar to the way we search for the telephone number of a person in the telephone directory. Binary search is the divide and conquer strategy.Read more about C Programming Language.
