About this course

C is a very flexible and well-established language thus making it the mother of all programming languages. Many programs, libraries, operating systems, etc are implemented in C. For example, in Linux, more than 85% of code is written in C. Getting into tech giants we need to have a solid knowledge of Data Structures that’s what we will be covering in this course.

Great Learning offers Post Graduate Programs in the field of Software Engineering for Data Science. You can join our software engineering course to develop your advanced Software Engineering skills required to build real-world, large-scale Data Science applications and earn a certificate from the International Institute of Information Technology Hyderabad.

Frequently Asked Questions

General Queries On This Free Course
What are the different types of data structures?

This is the basic knowledge for C programmers. There are mainly 8 data structures used by the programmer, they are as follow:

  1. Array
  2. Linked List
  3. Stacks
  4. Queues
  5. Hash Tables
  6. Trees
  7. Heaps
  8. Graphs
What is a Data Structure? Explain.

A data structure is a specific way of organizing data in a computer so that it can be used effectively. Data structures have a very wide and diverse scope of usage across the fields of Computer Science and Software Engineering.

It is the actual way that a computer can understand the language and the program you want to execute. 


What is the Data Structure Give Example ?

Examples for data structures are Arrays, Linked Lists, Queue, Stack, Hash table, Trees, Heaps, Graphs.


What are the Primitive Data Types ?

The primitive data types are:

  • Character- character can be written as character & char
  • Integer- integer can be written as an integer, int, short, long, a byte with many varieties of naming
  • Floating point number – it can be written as float, double, real, double precision 
  • Fixed point number – it can be written as fixed with a variety of precisions and programmed scale.
  • Boolean - logical values true and false.

The above primitives are generally supported more or less directly by computer hardware, except possibly for floating-point, so operations on such primitives are usually fairly efficient. Some programming languages support text strings as primitive

Which data structure is best?

An array is the best data structure as arrays are the simplest data structures that store items of the same data type. A simple application of Arrays can be storing data in tabular format.


How is a data structure used in real life?
  1. Leader-board arrangement of a game can be done simply through arrays to store score and sort them in descending order to clearly make out the rank of each player in the game.
  2. Images are interlinked with each other. So, an image viewer software uses a linked list to view the previous and the next images using the previous and next buttons
  3. While switching multiple applications, windows use a circular queue.
  4. Call logs in mobile use Stack.
What are the advantages of data structures?

Efficient Memory use, Reusability and Abstraction.

Data structures are the basic building blocks of any programming language, complex computations.
