    question on random file access

    let's say i have an ifstream and an ofstream. how can i read/write to a specific byte on a file?
    the only way i know how so far is by reading the whole file into memory and doing it there. thanks in advance

    Use ifstream::seekg() and ofstream::seekp()
    Look them up on MSDN for details.
