= The ''for'' Loop =

''Part of'' TutorialFundamentals

== Description ==

How to do the same thing over and over again.

== Example ==

Most people don't like to do monotonous tasks over and over again (especially not a lazy programmer). That's where the '''for''' loop comes in. You could write a program like this:
{{{
    writef("1\n");
    writef("2\n");
    writef("3\n");
    writef("4\n");
    ...
}}}
but that's no fun. The '''for''' statement allows the programmer step back and just say to the computer, "count from 1 to 10, and print each number."

==== Example Code ====
{{{
#!d
import std.stdio;

int main() 
{
  for (int i = 1; i <= 10; i++)
    writefln(i);
  return 0;
}
}}}

== Equivalent Example in QuickBASIC ==

{{{
DIM I%

FOR I% = 1 TO 10
   PRINT I%
NEXT I%
}}}

== Output ==

{{{
1
2
3
4
5
6
7
8
9
10
}}}
