WebTo search an element from an array using the binary search technique in C++ programming, you have to ask the user to enter any 10 elements for the array and then enter the element or number to be searched. After searching the element using the binary search technique, if it is available in the list, display the position of the element. WebA binary search might be more efficient. Because the array primes contains 25 numbers, the indices into the array range from 0 to 24. Using the step-by-step instructions from the previous article, we start by letting min = 0 and max = 24.

WebA binary search is an algorithm to find a particular element in the list. Suppose we have a list of thousand elements, and we need to get an index position of a particular element. We can find the element's index position very fast using the binary search algorithm. WebBinary search follows the divide and conquer approach where the list is divided into two halves and the item is compared with the middle element each time. If the middle element is less than the element to be searched, then we search for the element in the first half of the list; otherwise, we search for the element in the second half of the list.
