In our first part on pointers, we covered the basics and common pitfalls of pointers in C. If we had to break it down into one sentence, the main principle of pointers is that they are simply data ...

we covered the basics of pointers in C, and went on to more complex arrangements and pointer arithmetic in the second part. Both times, we focused solely on pointers representing data in memory.

Here's a C/C++ program that converts decimal numbers ranging from 0 to 99,999 to binary and BCD formats. Using a simple algorithm in conjunction with pointer arithmetic and bitwise shifting ...
