    Replace #include<iostream.h> with #include <stdio.h> as well.
    And it's int main(), not void main().

    and learn to indent your code... ow my eye.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    Not to mention this is not C++... this is C-- (my word for non-standard C++!).

    Not that it has anything to do with the "conversion", but there are some erroneous semicolons floating about your program.
    Code:
    if(yr<1928) ;  <--???
    yr-=1928;
    j=(yr)/4;
    yr%=7;
    cout<<"Enter month:";
    cin>>mo;
    if(mo<1 || mo>12) ;  <--???
    cout<<"Enter day:";
    cin>>dy;
    if(dy<1 || dy>31) ;  <--???

    I think you need to re-acquaint yourself with the space bar and tab button.
