| | those functions sort double arrays, not int arrays. Either change your int arrays to double, or change the functions to sort int arrays. The two can not be mixed. >>double sortArray(double [], int); this is the wrong prototype. Actual function does not have those parameters. |

| | The destructor is not deallocating enough memory -- it heas a memory leak. For every new[] there must be a corresponding delete[]. You need to add a loop similar to the one that is in the constructor. As for your problem -- hummm I'll have to think about it awhile. … |
