");scanf("%d",&n);printf("Enter … Now that you have understood the basics of Programming in C, check out the training provided by Edureka on many technologies like Java, Spring and  many more, a trusted online learning company with a network of more than 250,000 satisfied learners spread across the globe. It can be applied to sequential storage structures like files, linked lists,etc. The linear search is probably the oldest search algorithm, it goes through each and every element of the unsorted array and look for the key, you are searching for. In this C++ program we have to search an element in a given array using linear search algorithm. In the best case, it's present at the beginning of the list, in the worst-case, element is present at the end. Linear Search . The user will have to add the total numbers want to add in array and the single number that is needed to be searched. Binary Search In C: Everything You Need To Know Binary Search. With this, we come to the end of this blog on ‘Linear Search in C’. Linear Search in C. #includeint main(){int a[20],i,x,n;printf("How many elements?
