Sorted directory - C++ program:

Write a program in c to sorting a directory.

int main( int argc, char *argv[] )

{

    if( argc < 2 || argc > 3 )

        {

        cerr << "Usage:  directry [options] filespec" << endl << endl;

        cerr << "Options:" << endl;

        cerr << "\t-sd\tsort by date" << endl;

        cerr << "\t-sn\tsort by name" << endl;

        cerr << "\t-ss\tsort by size" << endl;

        exit(1);

        }

    int path;                      

    Directory::sortOrder sorting = Directory::byName;

    if( argc != 3 )

        path = 1;

    else

        {

        path = 2;

        if( strcmp( argv[1], "-sn" ) == 0 )

            sorting = Directory::byName;

        else if( strcmp( argv[1], "-sd" ) == 0 )

            sorting = Directory::byDate;

        else if( strcmp( argv[1], "-ss" ) == 0 )

            sorting = Directory::bySize;

        }

    Directory sortedDirectory( argv[path], sorting );

    cout << sortedDirectory;

    return 0;
