    as im having amnesia i'm not very sure about this but there are converters who can convert c code to c++ and i guess there will be some apps who do the reversed thing....this is a c to c++ converter
    i think you should be able to find a reversed prog by using this "awsome link"

    cout --> printf
    cin --> scanf / fgets
    class methods --> functions
    class data --> variables and/or structures
