Performing dynamic memory allocation

In this recipe, we will learn how to dynamically allocate some memory. We will also learn how to increase the number of memory blocks, how to decrease the number of allocated memory blocks, and how to free up memory. 

How to do it...

We will ask the user how many memory blocks need to be allocated, and we will dynamically allocate that number of memory blocks. The user will then be asked to assign integer values to those memory blocks. After that, the user will be asked how many more additional blocks need to be allocated. Similarly, the user will be asked how many memory blocks need to be reduced too. The following are the steps to be performed in order to dynamically allocate...
