Koding Tampil Data

Kali ini saya akan memposting koding pemrograman “Tampil Data”, yaitu koding yang jika masukkan data yang sudah ada akan muncul tulisan error. Contoh dalam kehidupan sehari-harinya adalah ketika membuat Username suatu akun.

Program Tampil_data;
Uses wincrt;
Var
  n, i, j:integer;
  x:array [1..100] of integer;

Begin
  Write ('Masukkan banyak data ='); readln (n);

  Writeln;

  for i:=1 to n do
  Begin
       Write ('Data ke-',i,'= '); readln (x[i]);
  End;


  Writeln;

  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;

  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;

  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;


  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;

  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;

  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;

  for i:=1 to n-1 do
  for j:=i+1 to n do
  Begin
       if x[i]=x[j] then
          x[j]:=x[j+1]
  End;


  for i:=1 to n do
  if x[i]=x[i+1] then
     Writeln
  else
      begin
      Writeln ('Data ke-',i,'= ',x[i]);
      end;
   
End.
