Repeat steps 3 … Mention it in the comments section of this “Linear Search in C” blog and we will get back to you as soon as possible. The program for linear search is written in C language. Linear Search . If x does not match with any of the elements then return -1. Searching is the process of finding particular value in an array. In Linear search, we search an element or value in a given array by traversing the array from the starting, till the desired element or value is found. Every item is checked and if a match is found then that particular item is returned, otherwise the search continues till the end of the data collection. Linear search is a very simple and basic search algorithm. Linear Search in C programming 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. If the target is equal to the element at index 0, then we have found the target. Sorting and Searching. In this type of search, a sequential search is made over all items one by one. If the element is successfully found in the list then the index of that element is returned. 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. What is Embedded C programming and how is it different? It is also known as a sequential search.
