    Re: Need help with Pascal program on array

    For this I would be looking to have an array of record with a record holding the info for each guest. It's a very long time since I last programmed in pascal! - and haven't got easy access to a pascal compiler. So something along the lines of (not tried)
    Code:
    Program WeddingGuests(input, output);
    Const MaxGuests = 500;
          veg = 'V';
          nonVeg = 'N';
    
    Type Guest = Record
                     mealpreference :char;
                     name : string
                 End;
    
    Var guests : array[1..maxGuests] of Guest;
        totalguest : integer;
        gnam : string;
        p : char;
        g : integer;
    
    Begin
         Repeat
              Writeln('Enter total number of invited guests');
              Readln(totalguest);
              if (totalguest < 0) OR (totalguest > maxGuests) then
                  Writeln('Invalid number of guests')
         Until (totalguest > 0) AND (totalguest <= maxGuests);
         for g := 1 to totalguest do
         begin
             Writeln('Enter name of guests');
             Readln (gnam);
             guests[g].name := gnam;
    
            Repeat
               Writeln ('enter meal preference');
               Readln (p);
               If ( p = veg) OR (p = nonVeg) then
                   guests[g].mealpreference := p
               Else
                 Writeln('invalid meal type re-enter until valid')
            Until (p = veg) OR (p = nonVeg)
         End
    End.
    PS OK got access to a pascal compiler and the code compiles OK.
