Our function will take three arguments: the array to search, the number of elements in the array, and a value to search for. And function to search for an element. Experience. Linear Search in C++. Linear search is a searching algorithm which is used to detect the presence of a number in an array and if present, it locates its position in that array. a complete linear search program using array. In my previous posts related to array, I have explained how easily we can search an element in array without using pointer.Here in this post we will see how to search an element in array using … So "n" should be a pointer. Required knowledge. A simple approach is to do a linear search, i.e Start from the leftmost element of arr [] and one by one compare x with each element of arr [] If x matches with an element, return the index. By continuing to use this website, you agree to their use. What is a Linear Search? Linear Search in C and Linear Search Using Functions Linear Search in C Linear search in c programming: The following code implements linear search ( Searching algorithm ) which is used to find whether a given number is present in an array and if it is present then at what location it occurs. Linear Searching is also popularly known as Sequential Search Technique. To Find an Element in an Array using Sequential Search Algorithm Technique, we need to traverse over the complete Array and Compare every Element of the Array with the Search Element. int n = sizeof(arr) / sizeof(arr [0]); int x = 4; int index = search (arr, n, x); if (index == -1) cout << "Element is not present in the array"; else.
