与宏!

#include<stdio.h>
#define x001(a) a
#define x002(a) x001(a);x001(a)
#define x004(a) x002(a);x002(a)
#define x008(a) x004(a);x004(a)
#define x010(a) x008(a);x008(a)
#define x020(a) x010(a);x010(a)
#define x040(a) x020(a);x020(a)
#define x080(a) x040(a);x040(a)
#define x100(a) x080(a);x080(a)
#define x200(a) x100(a);x100(a)
#define x3e8(a) x200(a);x100(a);x080(a);x040(a);x020(a);x008(a)
int main(int argc, char **argv)
{
  int i = 0;
  x3e8(printf("%d\n", ++i));
  return 0;
}

我觉得这个答案会很简单，很容易理解。

int print1000(int num=1)
{
    printf("%d\n", num);

    // it will check first the num is less than 1000. 
    // If yes then call recursive function to print
    return num<1000 && print1000(++num); 
}

int main()
{
    print1000();
    return 0;        
}

只需使用std::copy()和一个特殊的迭代器。

#include <algorithm>
#include <iostream>
#include <iterator>

struct number_iterator
{
    typedef std::input_iterator_tag iterator_category;
    typedef int                     value_type;
    typedef std::size_t             difference_type;
    typedef int*                    pointer;
    typedef int&                    reference;

    number_iterator(int v): value(v)                {}
    bool operator != (number_iterator const& rhs)   { return value != rhs.value;}
    number_iterator operator++()                    { ++value; return *this;}
    int operator*()                                 { return value; }
    int value;
};



int main()
{
    std::copy(number_iterator(1), 
              number_iterator(1001), 
              std::ostream_iterator<int>(std::cout, " "));
}

你可以非常简单地使用递归和强制错误…

另外，请原谅我的c++代码非常草率。

void print_number(uint number)
{
    try
    {
        print_number(number-1);
    }
    catch(int e) {}
    printf("%d", number+1);
}

void main()
{
    print_number(1001);
}

#include <stdio.h>
#include <assert.h>

void foo( int n )
{
 printf("%d\n", n);
 assert( n > 0 );
 foo(--n); 
}

int main()
{
 foo( 1000 );
 getchar();
}

既然对bug没有限制…

int i=1; int main() { int j=i/(i-1001); printf("%d\n", i++); main(); }

或者更好(?)，

#include <stdlib.h>
#include <signal.h>

int i=1;
int foo() { int j=i/(i-1001); printf("%d\n", i++); foo(); }

int main()
{
        signal(SIGFPE, exit);
        foo();
}
