使用C语言判断栈的方向实例

#include <stdio.h>static int stack_direction = 0;static void FindStackDirection(){  static char *addr = NULL;  auto char dummy;  if (NULL == addr) {    addr = &dummy;    FindStackDirection();  //递归调用，让dummy两次被定义，并一先一后入栈  } else {    if (&dummy > addr) {  //两次地址相比较，后入栈的dummy地址大于先前的地址则说明是往高地址增长      stack_direction = 1;    } else {      stack_direction = -1;    }  }}int main(int argc, char const *argv[]){  FindStackDirection();  if (1 == stack_direction) {    puts("stack grew upward");  } else {    puts("stack grew downward");  }  return 0;}
