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 ...

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 ...

Once again, pointers are simply memory addresses, and to fully utilize this similarity, C provides the concept of function pointers.

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 ...

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 ...

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.
