Integer sequence

Integer sequence is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Create a program that, when run, would display all integers from 1 to ∞ (or any relevant implementation limit) if given enough time.

BASIC

<lang basic>5 LET A = 0 10 LET A = A + 1 20 PRINT A 30 GOTO 10</lang>

C

<lang c>#include <stdio>

int main() {

 uint_32 i = 0;
 while(1)
 {
   printf("%u\n", ++i);
 }

 return 0;

}</lang>

C++

<lang cpp>#include <iostream>

int main() {

 uint_32 i = 0;
 while(true)
 {
   std::cout << ++i << std::endl;
 }

 return 0;

}</lang>

Perl

<lang perl>my $i = 0; while(1) {

 print ++$i . "\n";

} </lang>
