Write and use data stored in data files...

Hi there. I guess you are familiar with old game called DOOM. If you are, you must know that all game data (models, levels, sounds etc.) situated in file called doom.wxd (takes 5-7 Mb). Well it just an example - now almoust all games have few data files like this. So let's jump to the question: "How can you write all that different kinds of data to a binary file and retrive it from there ?". Any help will be very userful. ThanX

FILE* fp = fopen(thefile,"rb+");

fread(yourdata,numberofitemstoread,sizeofeachitem, fp);
//do whatever

fwrite(yourdata,numberofitemstowrite,sizeofeachite m,fp);

In C you can only use file pointers. In C++ you can use file pointers or streams to manipulate files.
