Searching in Arrays

ICSE Computer Applications


Searching for something is a fairly common activity we do in our daily lives.

To call your friend, you search for his or her name in the contacts of your phone.

To study a particular chapter in your book, your search for its name in the table of contents and find out its starting page number. I can go on and on with such examples, but I hope you got the point.

Searching is a common activity in programming as well. As arrays hold a collection of values, often in our programs we need to check if a particular value is present in our array or not.

There are many ways to search an array. In this course we will look at two of them — Linear Search and Binary search as that’s what ICSE has mentioned in the syllabus.
