Loops/Continue

From Rosetta Code
Task
Loops/Continue
You are encouraged to solve this task according to the task description, using any language you may know.

Show the following output using one loop.

1, 2, 3, 4, 5
6, 7, 8, 9, 10

Ada

Ada has no continue reserved word, nor does it need one. The continue reserved word is only syntactic sugar for operations that can be achieved without it as in the following example.

<ada> with Ada.Text_Io; use Ada.Text_Io;

procedure Loop_Continue is begin

  for I in 1..10 loop
     Put(Integer'Image(I));
     if I mod 5 = 0 then
        New_Line;
     else
        Put(",");
     end if;
  end loop;

end Loop_Continue; </ada>

C

Translation of: C++

<c>for(int i = 1;i <= 10; i++){

  printf("%d", i);
  if(i % 5 == 0){
     printf("\n");
     continue;
  }
  printf(", ");

}</c>

C++

Translation of: Java

<cpp>for(int i = 1;i <= 10; i++){

  cout << i;
  if(i % 5 == 0){
     cout << endl;
     continue;
  }
  cout << ", ";

}</cpp>

ColdFusion

Remove the leading space from the line break tag.

<cfscript>
  for( i = 1; i <= 10; i++ )
  {
    writeOutput( i );
    if( 0 == i % 5 )
    {
      writeOutput( "< br />" );
      continue;
    }
    writeOutput( "," );
  }
</cfscript>

D

<d>for(int i = 1;i <= 10; i++){

 writef(i);
 if(i % 5 == 0){
   writefln();
   continue;
 }
 writef(", ");

}</d>

Fortran

Works with: Fortran version 90 and later
DO i = 1, 10
  IF (MOD(i, 5) == 0) THEN
    WRITE(*, "(I0)") i
  ELSE
    WRITE(*, "(I0,A)", ADVANCE="NO") i, ", "
  ENDIF
END DO

J

J is array-oriented, so there is very little need for loops. For example, one could satisfy this task this way:

_2}."1'lq<, >'8!:2>:i.2 5

J does support loops for those times they can't be avoided (just like many languages support gotos for those time they can't be avoided).

   3 : 0 ] 10 
        z=.''
        for_i. 1 + i.y do.
            z =. z , ": i

             if. 0 = 5 | i do.
                  z 1!:2 ]2 
                  z =. ''
                  continue. 
             end. 

             z =. z , ', '
        end.
     i.0 0
   )

Though it's rare to see J code like this.


Java

<java>for(int i = 1;i <= 10; i++){

  System.out.print(i);
  if(i % 5 == 0){
     System.out.println();
     continue;
  }
  System.out.print(", ");

}</java>

MAXScript

for i in 1 to 10 do
(
    format "%" i
    if mod i 5 == 0 then
    (
        format "\n"
        continue
    )   continue
    format ", "
)

Modula-3

Modula-3 defines the keyword RAISE as an exception, but when it is used with no arguments, it works just like continue in C.

Module code and imports are omitted.

FOR i := 1 TO 10 DO
  IO.PutInt(i);
  IF i MOD 5 = 0 THEN
    IO.Put("\n");
    RETURN;
  END;
  IO.Put(", ");
END;


Perl

<perl>foreach (1..10) {

   print $_;
   if ($_ % 5 == 0) {
       print "\n";
       next;
   }
   print ', ';

}</perl>

PHP

<php>for ($i = 1; $i <= 10; $i++) {

   echo $i;
   if ($i % 5 == 0) {
       echo "\n";
       continue;
   }
   echo ', ';

}</php>

Pop11

lvars i;
for i from 1 to 10 do
   printf(i, '%p');
   if i rem 5 = 0 then
       printf('\n');
       nextloop;
   endif;
   printf(', ')
endfor;

Python

<python>for i in xrange(1,11):

   if i % 5 == 0:
       print i
       continue
   print i, ",",</python>

Ruby

for i in 1..10 do

  print i
  if i % 5 == 0 then
     puts
     next
  end
  print ', '

end

UnixPipes

yes \ | cat -n | head -n 10 | xargs -n 5 echo | tr ' ' ,

Visual Basic .NET

       For i = 1 To 10
           Console.Write(i)
           If i Mod 5 = 0 Then
               Console.WriteLine()
           Else
               Console.Write(", ")
           End If
       Next
