    Reading and Writing Data From ifstream to *STL Container* in *Binary*

    Hi.
    I am working on a simple program that reads data into memory in binary. It then write the data from memory to a second file in memory.

    Is it possible to read from ifstream straight to an STL container instead of having to go through dynamic memory allocation?

    Thanks,
    Kuphryn

    You could probably do something like that. Loop through your file and read each record into a temporary structure and then copy this structure into the container.

    However, it's often easier and more efficient to store pointers to the objects in the containers. In which case you'd need to allocate memory dynamically, as a copy of the pointer would be entered into the container rather than a copy of the object itself.
