- The
new operator can be used to allocate a specified amount of storage for a given type at run time; a pointer to the start of the storage is returned
- After allocation, you can access the storage through the pointer as if it were an array - i.e., by using
[] to index individual elements
- It is important to release the storage using the
delete operator when it is no longer required; failure to do this can lead to memory leaks (depending on the nature of your program)
- It is often easier to use a vector than allocate storage manually in this fashion
