C++: memory deallocation

Alessandro · 2011-11-13T19:22:18

Hi, I surely misunderstood something about dynamic memory allocation and deallocation. I have this simple code that fills a dynamic array with values: float *map; int iterations=9999999; map = new float[iterations]; for (int i=0; i<iterations; i++) { map=someRandFloat(); } The above routine uses about 40MB of memory. After that, I'd like to deallocate and free the memory, and so I run: delete map; However, the Task Manager shows that the program is still using the same 40MB of memory. Thanks

To check if the memory is freed, you could check with the memory pane while debugging, when calling delete [], you should see the memory block being deleted (bytes reset to 0xCD or 0xDD something like that).
