Definition: Linear search is also called sequential search; Linear search is a method for searching a value within a array. In the best-case scenario, the element is present at the beginning of the list and in the worst-case, it is present at the end. C++ Program Linear Search in Array Write a C++ program to search an element in an array using linear search. Let’s go through the following program so as to understand how it helps us find the requisite element in the list using the linear search algorithm. int main(){ int array[100], search, c, n; printf("Enter number of elements in array\n"); scanf("%d", &n); for (c = 0; c < n; c++) scanf("%d", &array[c]); printf("Enter a number to search\n"); scanf("%d", &search); for (c = 0; c < n; c++) { if (array[c] == search) /* If required element is found */ { printf("%d is present at location %d.\n", search, c+1); break; } } if (c == n) printf("%d isn't present in the array.\n", search); In the code below we will print all locations at which required element is found and also the number of times it occurs in the list. In linear search algorithm, we compare targeted element with each element of the array. Here’s simple Program to search an element in an array using linear search in C Programming Language. In this algorithm each element of array is compared with the targeted element sequentially. Everything You Need To Know About Sorting Algorithms In C, Fibonacci Series In C : A Quick Start To C Programming. We’ll talk about more linear search and then code a program in C language. Linear search in C to find whether a number is present in an array. C Program for LINEAR SEARCH. C Program For Linear Search Algorithm. What is Searching ? It is a basic search technique to find an element from the collection of elements(in sequence) or from an array that why it is also known as Sequential Search.

Binary search algorithm searches the target value within a sorted array.. To perform a binary search array must be sorted, it should either be in ascending or descending order. Linear Search . Wherever this main method is, the main method will be executed first. The program code to implement a linear search is as given below. All the elements need not be in sorted order like binary search.
