- C programming language - Need to learn about pointers

[lololafripouille]

Hello

I don't know where to post this.
It is not related to MikroE hardware of software but maybe that this can be a topic of a future ticket on their great http://learn.mikroe.com/ website.

I haven't followed electronic or programming studies so it is maybe the reason why I don't understand well the pointer concept.

- I tried to learn with online book or tutorial but I found nothing about what I can do with pointer that I can't do without.
- What is the impact of the use of pointers in a program that can be done without ? ( more code efficient ? more speed ? )

I just need concrete and real exemple that use pointers and the reason why they are used intead of global variables.
If someone have that kind of skills or a book or a tutorial, it will be very nice to share this with me.

Thank you everyone for your help

Pointer is like array but there is no Index system on other hand you can store unlimited memory based data and you don't need to initialized the memory before used.
