Binary search array c++
WebThe bsearch () function in C++ performs a binary search of an element in an array of elements and returns a pointer to the element if found. The bsearch () function requires all elements less than the element to be searched to the left of it in the array. WebApr 10, 2024 · Binary search is an algorithm used to find an element i.e., key in a sorted array. Binary algorithm works as below − Let us say that array is ‘arr’. Sort the array in ascending or descending order. Initialize low = 0 and high = n-1 (n = number of elements) and calculate middle as middle = low + (high-low)/2.
