Memory allocation in C++

[Kon V]

Hi,
I was hoping somebody might be kind enough to give me a quick run down
memory allocation and reallocation in C++. When should memory be
allocated/reallocated/deleted? I've ran into memory issues on the last
assignment with huge amounts of data, and while some of it is most
likely due to my own system's limitations, I also feel like I'm not
doing properly myself.
Should I call delete on everything involving pointers?

In fact, it has little to do with pointers, but with "new".  Just that new returns a pointer to the dynamic object.  You want to de-allocate object when it is no longer needed.
