Now I think you have a doubt "Why Linear search basic?" In this type of searching, we simply traverse the list completely and match each element of the list with the item whose location is to be found. All the elements need not be in sorted order like binary search. Problem Definition. It is also known as a sequential search. It is also known as a sequential search. If the element is successfully found in the list then the index of that element is returned. What is Objective-C: Why Should You Learn It? C C++ Server Side Programming Programming. How To Carry Out Swapping of Two Numbers in C? Compare the search element with the first element in the list. If the target is equal to the element at index 0, then we have found the target. C/C++ Program for Linear Search? The worst case time complexity for linear search is O(n). A binary search technique works only on a sorted array, so an array must be sorted to apply binary search on the array. The program output is also shown in below. Linear search programming The below code explains linear search. Linear Search Program in C.Linear Search is the simplest form of searching. a[n-1]. If it's present, then at what location it occurs. 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. The idea is to start traversing the array and compare elements of the array one by one starting from the first element with the given element until a match is found or the end of the array is reached. Linear search is a very simple search algorithm. Binary search is faster than the linear search. Searching is the process of finding particular value in an array. Linear Search Linear search is the simplest search algorithm and often called sequential search. Sorting and Searching. The program code to implement a linear search is as given below. Linear search for multiple occurrences and using a function. int main(){  int array, 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.
