[Dev-C++] Memory problem

[Marcos C. <ca...@un...>]

Hello!

I am with a memory problem. I need to create three objects in the
Dev-C++ with 1024x1204 positions of double. The program compels
normally, but it does not work because not obtain place enough in memory
for all objects. What I can do to make this? My program work with
pointers for the objects.

Thanks for any help.

I assume C++:

double (*p)[1024]=double int[1024][1024];

// ...

delete[] p;



But I strongly recommend:

#include <vector>

// ...

using std::vector;

vector<vector<double> >array(1024, vector<double>(1024));

// ...

// The container object goes out of scope and clears itself
automatically.

Sorry I am after the regular format and my emails will suck for some
days. :)

Hello,

I made an implementation with STL and now I want to develop another
equivalent with pointers to compare them.  I also want to compare the
results gotten with different compilers. In relation to STL implementation,
the results of DEV-C++ had been superior in the majority of the times.

Thanks for the help.
