Saving and loading arrays in C++

How do I save and load arrays to and from a text file in C++?

man 2 open
man 2 read
man 2 write
man 2 close

That makes no sense... can you elaborate?

unix man pages. RTFM or GTFO

man 2 open read write close
more concise, no?

Before you follow the other advice in this thread and write C code in C++, check out Boost's serialisation library (I presume you already know iostreams).

>>1
#include <fstream>
ofstream ofs("filename", ios::out|ios::binary);
ofs.write((char*)array, sizeof(array_type)*size of array);
ofs.close();
???
return

Don't forget the STDs

template<typename T>
void save_vector(const vector<T>& v, ostream& out)
{
    copy(v.begin(), v.end(), ostream_iterator<T>(out, "\n"));
}

template<typename T>
vector<T> load_vector(istream& in)
{
    vector v;
    copy(istream_iterator<T>(in), istream_iterator<T>(), back_inserter(v));
    return v;
}

ooh pretty, no char *.

ed to wonder why   there was no   reason why a   twat like you   ARE CODING TIMES   A MILLION AND   soon one billion   transistor processors where   the actual computing   takes place in   my nightgown while   humming the SICP   video lectures and   then read the   Design of Everyday   Things and About   design and you   can run the   computation another day.

Meditate on lexical and!
