    Code:
    #include <fstream>
    
    ifstream infile("Filename goes here");
    ofstream outfile("Filename goes here");
    infile would be the file you read from, outfile the file you write to.

    They are different modifying options. For example, ios::nocreate will not create a file if it does not exist. If not there, a file will be created if it doesn't exist.

    You can't write to files using ifstream, you have to use ofstream.
    Then you can call ofstream::write(buffer, length);
