#include <fstream>
    using namespace std;
    int main ()
    {
        long pos;
        ofstream outfile;
        outfile.open ("Example.txt");
        outfile.write ("This is a Sample",16);
        pos = outfile.tellp();
        outfile.seekp (pos - 7);
        outfile.write (" Ex", 6);
        outfile.close();
        return 0;
    }

1. This is a Sample
