Pointers in C++ Programming with Dynamic Memory Allocations - Free Download Tutorials

In C and C++, pointers allow you direct control of the way you access memory. This becomes very useful when learning to use build complex data structures or trying to save space when allocating memory.

One of the most basic ways pointers help is when you want to dynamically set the size of an array based on an external input not known beforehand to the compiler or you may want to change the size of the array in runtime. In C++, arrays must have a constant size which can’t be changed, but with pointers, you can allocate just the space you need, allowing you to improve your program’s space efficiency and make the shape of your data as flexible as the user needs.
