Answer 1

There is no compression built into C++, you will have to use a suitable library. The most portable C++ library is boost -- http://www.boost.org .



Here's how to compress the file "test.txt" with boost:



#include

#include

#include

#include

#include

using namespace std;

using namespace boost::iostreams;

int main()

{

ifstream in("test.txt", ios_base::in | ios_base::binary);

ofstream file("test.z", ios_base::out | ios_base::binary);

filtering_streambuf

out;

out.push(zlib_compressor());

out.push(file);

boost::iostreams::copy(in, out);

}



to compile, remember to link boost_iostreams library.



There are many other libraries that offer compression too.

Answer 2

You can use the method call



system() or exec()



where you pass the parameters as the zip file program (eg zip), flags for that program and the file name.
