About the Complete Guide to Arrays
The dream of every programmer is to become not just a good, but also a great programmer. We all want to achieve our goals and to achieve our goals, we must have a great plan with us. In this context, we have decided to provide a complete guide for Arrays interview preparation, which will help you to tackle the problems that are mostly asked in the interview, such as What is an Array, What is Array in C language, How do you initialize an Array in C, How to sort an Array, etc. We have also covered the topics such as Top Theoretical interview questions and Top interview coding questions in this complete guide for Array interview preparation.
Basic terminologies of array
While learning about Array Data Structures in this Complete Guide on Arrays, you will come across some common terms that will be used multiple times. Some of these terms are:
- Array Index: In an array, elements are identified by their indexes. Array index starts from 0.
- Array element: Elements are items stored in an array and can be accessed by their index
- Array Length: The length of an array is determined by the number of elements it can contain.
Why Array Data Structures is needed?
Assume there is a class of five students and if we have to keep records of their marks in examination then, we can do this by declaring five variables individual and keeping track of records but what if the number of students becomes very large, it would be challenging to manipulate and maintain the data.
What it means is that, we can use normal variables (v1, v2, v3, ..) when we have a small number of objects. But if we want to store a large number of instances, it becomes difficult to manage them with normal variables. The idea of an array is to represent many instances in one variable.
