I declared a dynamic array like this: double *DEMDATA= (new double[1024*1024]); How can i be sure that memory is correctly allocated for this array ? I suppose i need to use the malloc() function, but how ? Thanks

new throws an exception if the allocation fails. if no exception is thrown, everything is fine.

If you're using C++, you almost certainly do not want to use malloc. new and delete/delete[] should serve all of your C++ dynamic memory allocation needs.
