Could anyone translate this short Pascal program to a C or C++ program??
I know nothing about pascal, so...
program dds;

type
  trec = packed record
           typ : array[1..  2] of char;
           psd : array[1.. 30] of char;
           fic : array[1..  8] of char;
           num : array[1..  5] of char;
         end;
var
  rec   : trec;
  f1    : file of trec;
  f2    : text;
  psd1  : string;
  psd2  : string;
  pth1  : string;
  pth2  : string;
  i     : integer;
  j     : integer;
begin
  pth1:=paramstr(1);assign(f1,pth1);reset(f1);
  psd1:=paramstr(2);
  i:=length(psd1);
  while not(eof(f1))
    do
    begin
      psd2:='';
      read(f1,rec);
      for j:=1 to i do psd2:=psd2+rec.psd[j];
      if (psd1 = psd2) then writeln(rec.psd);
    end;
  close(f1);
(*  close(f2);*)
end.

Here's a go at the translation.  I did
not compile this, so there may be some typeos

//
// make sure you set structure packing to be 1 byte in compile options or compiler pragma
//
typedef trec
{
char typ[2];
char psd[30];
char fic[ 8]r;
char num[5];
};
 
rec  trec;
FILE *f1;

psd1 : string;
psd2 : string;
pth1 : string;
pth2 : string;
i : integer;
j : integer;

int main(int argc, char *argv[])
{

      //
      // you should check arguments here to avoid protect violations or garbage
      //

      f1 = fopen(argv[1],"rb");

      i:=strlen(psd1);

      while not(eof(f1))
      {       
            //
            // read a record from the file
            //      
            fread(rec, sizeof(trec), 1, f1);

            //
            // if the psd field of rec is equal to the second param, then
            // print it out
            //
            if memcmp(argv[2], rec.psd, i) then printf("%s\n", ref.psd);
      }
      fclose(f1);
}
