      speeds[1] = 'b';
      speeds[2] = 'c';

      // ...

      delete [] speeds;  // releases the memory allocated for the array, from now on the array can't be used

Description |  | Deletes or releases the memory allocated for an object with the new oeprator. The keyword delete is typically used similarly to the applications in the above example. In this example, a new array of chars called "speeds" is created, used and then deleted. Operators new and delete can only be used with simple datatypes: int, long or char.
