Why do you need to learn this C pointers module ?

This Tutorial helps you learn the pointer concepts of C programming language from scratch quickly and effectively.

Learning about pointers has always been trickier for students, beginners, expert engineers etc.,

If you…

• Are not sure where to start learning C Pointers.

• Are frustrated with copy-n-paste of C Pointers code from others without really understanding it.

• Cannot add efficient and compact code using C because you don’t know how to get much out of the language.

Then,

• C-Pointers.com is a good place to start.

Teaching Approach in this module

C-Pointers.com takes the approach of explaining pointer concepts in a unique way

• Every chapter has a uniform template, and teaches you to write

  • Table of Equations

  • Table of Expressions

  • Table of Size (for Expressions)

  • Table of Type (for Expressions)

  • Table of Operations (for Expression)

  • Table of Address/Value (for Expression)

  • Table of Function Prototype (for Expression)

• The moment you see any complicated C statements having *, [], ->, &

  • Make sure you are comfortable and capable of writing down above tables quickly

  • In the beginning days, you can write the tables on sheet of paper

  • At later stages, you can quickly load them in your mind

• Kindly read the modules, chapters in the same order as mentioned below
