我重新制定了比尔提出的伟大惯例，使其更加普遍:

void printMe () 
{
    int i = 1;
    startPrintMe:
    printf ("%d\n", i);
    void *labelPtr = &&startPrintMe + (&&exitPrintMe - &&startPrintMe) * (i++ / 1000);
    goto *labelPtr;
    exitPrintMe:
}

更新:第二种方法需要2个功能:

void exitMe(){}
void printMe ()
{
    static int i = 1; // or 1001
    i = i * !!(1001 - i) + !(1001 - i); // makes function reusable
    printf ("%d\n", i);
    (typeof(void (*)())[]){printMe, exitMe} [!(1000-i++)](); // :)
}

对于这两种情况，都可以通过简单地调用来启动打印

printMe();

已为GCC 4.2测试。

触发致命错误!这是文件，counup .c:

#include <stdio.h>
#define MAX 1000
int boom;
int foo(n) {
    boom = 1 / (MAX-n+1);
    printf("%d\n", n);
    foo(n+1);
}
int main() {
    foo(1);
}

编译，然后在shell提示符下执行:

$ ./countup
1
2
3
...
996
997
998
999
1000
Floating point exception
$

这确实打印了从1到1000的数字，没有任何循环或条件!

#include <stdio.h>
void main(int i){printf("%d\n",i)&&i++<1000&&(*((int*)&i-1)-=5);} 

另一个:

#include <stdio.h>
int main(int i){return i<=1000&&printf("%d\n",i)&&main(++i);}

很难看透所有已经提出的解决方案，所以这可能是一个重复。

我想要一些相对简单的东西，只有纯C，而不是c++。它使用递归，但与我看到的其他解相反，它只做对数深度的递归。通过查找表可以避免使用条件。

typedef void (*func)(unsigned, unsigned);
void printLeaf(unsigned, unsigned);
void printRecurse(unsigned, unsigned);


func call[2] = { printRecurse, printLeaf };

/* All array members that are not initialized 
   explicitly are implicitly initialized to 0 
   according to the standard. */
unsigned strat[1000] = { 0, 1 };


void printLeaf(unsigned start, unsigned len) {
  printf("%u\n", start);
}

void printRecurse(unsigned start, unsigned len) {
  unsigned half0 = len / 2;
  unsigned half1 = len - half0;
  call[strat[half0]](start, half0);
  call[strat[half1]](start + half0, half1);
}

int main (int argc, char* argv[]) {
  printRecurse(0, 1000);
}

这甚至可以通过使用一个指针动态地完成。相关的变化:

unsigned* strat = 0;

int main (int argc, char* argv[]) {
  strat = calloc(N, sizeof(*strat));
  strat[1] = 1;
  printRecurse(0, N);
}

这是我的两个解。第一个是c#，第二个是C语言:

C#:

const int limit = 1000;

Action<int>[] actions = new Action<int>[2];
actions[0] = (n) => { Console.WriteLine(n); };
actions[1] = (n) => { Console.WriteLine(n);  actions[Math.Sign(limit - n-1)](n + 1); };

actions[1](0);

C:

#define sign(x) (( x >> 31 ) | ( (unsigned int)( -x ) >> 31 ))

void (*actions[3])(int);

void Action0(int n)
{
    printf("%d", n);
}

void Action1(int n)
{
    int index;
    printf("%d\n", n);
    index = sign(998-n)+1;
    actions[index](++n);
}

void main()
{
    actions[0] = &Action0;
    actions[1] = 0; //Not used
    actions[2] = &Action1;

    actions[2](0);
}

也可以通过简单的动态调度来实现(在Java中也适用):

#include<iostream>
using namespace std;

class U {
  public:
  virtual U* a(U* x) = 0; 
  virtual void p(int i) = 0;
  static U* t(U* x) { return x->a(x->a(x->a(x))); }
};

class S : public U {
  public:
  U* h;
  S(U* h) : h(h) {}
  virtual U* a(U* x) { return new S(new S(new S(h->a(x)))); }
  virtual void p(int i) { cout << i << endl; h->p(i+1); }
};

class Z : public U {
  public:
  virtual U* a(U* x) { return x; }
  virtual void p(int i) {}
};

int main(int argc, char** argv) {
  U::t(U::t(U::t(new S(new Z()))))->p(1);
}
