c++ - Can't delete dynamically allocated multidimensional array -

i can't delete dynamically generated arrays. there how create them:

template <typename t> t **allocatedynamic2darray(int nrows, int ncols){       t **dynamicarray;        dynamicarray = new t*[nrows];       for( int = 0 ; < nrows ; i++ ){         dynamicarray[i] = new t[ncols];         ( int j=0; j<ncols;j++){                 dynamicarray[i][j]= 0;             }         }       return dynamicarray; } 

and initialize 2d array using:

long double** h = allocatedynamic2darray<long double>(krylovdim+1,krylovdim); 

i can't delete it. here variations i've tried:

delete[] h; 

and gives error: "cannot delete objects not pointers" when apply this:

   (int qq=0; qq < krylovdim+1; qq++){         (int ww=0; ww < krylovdim; ww++){             delete [] h[qq][ww];         }         delete [] h[qq];     } 

is there way clean delete? i'm using visual studio 2010 if helps.

try this:

for (int qq=0; qq < krylovdim + 1; qq++) {     delete [] h[qq]; } delete [] h; 

so doing reverse of allocation process

for( int = 0 ; < nrows ; i++ ){     dynamicarray[i] = new t[ncols]; // instead of allocating delete !
