Pointers and Dynamic Access
Learn how to navigate arrays dynamically in C++ using pointers, moving forward and backward through data with simple user commands.
The project
You’ve been storing and printing data—like numbers or strings—using simple variables. But what if you want to directly access or manipulate memory? In C++, every variable is stored somewhere in memory, each with its own unique address.
If you could hold that address, move through a sequence of items, and even update them, you’d unlock the true power of low-level control.
For example, imagine a small memory block storing your weekly calorie data or step counts. Wouldn’t it be great if you could move a cursor through that data, forward or backward, to view or modify it dynamically?
Typing this:
Day 1 steps: 3000Day 2 steps: 4500Day 3 steps: 5000
It's helpful, but it’s still static.
What you need is a way to point to values in memory, move across them, and interact with them—like a dynamic navigation system for your data. ...
