C Program To Demonstrate Linear search

Posted on by Sandeepa Nadahalli
Write a C program to input N numbers (integers or reals) and store them in an array. Conduct a linear search for a given key number and report success or failure in the form of a suitable message.
Linear search is the basic searching algorithm, also called as sequential search. Algorithm search’s the element by comparing the each element in the list, until the desired element found. Read more about C Programming Language.
