bookDynamic Arrays

You can also allocate memory in RAM for arrays, which are called dynamic!

To create a dynamic array, just specify the type and number of elements you want in square brackets by declaring:

x = new int[5]; // Request memory
delete []x;    // Delete array pointed to x

Dynamic memory is extremely useful in many situations when your program doesn’t know how much place it needs. For instance, when your code needs to read a file or you want to create an array depending on user input.
