Pointers are a powerful feature in C and C++, but they come with risks that can lead to serious issues like NULL pointer crashes. By following these best practices—initializing pointers, checking for ...

I have a bunch of hard-coded global 3D arrays of floats. I can loop through an individual 3D array just fine, but I also want to loop through all the 3D arrays. So, I thought of creating a one ...

Pointers — you either love them, or you haven’t fully understood them yet. But before you storm off to the comment section now, pointers are indeed a polarizing subject and are both C&#… ...

Instead you use a pointer to locate the array and a value to indicate the number of elements. Frankly, I could program what I needed these days without including pointers in my code, so I hardly gave ...

I’ve worked with a number of 8-bit embedded systems and their C compilers where using clearer expressions (e.g. arrays) produced worse binary code, and using stupid pointer tricks compiled to ...

Programming in C can be tough for those new to the language, so Dennis Kubes wrote “ The 5-minute Guide to C Pointers,” and put it on his blog. Only four code snippets are needed for Kubes to ...

Just remember casting pointer to int is a bad idea. When someone port the code to 64bit the pointer will be 64bit but int usually stay at 32bit.
