/* Example of deep recursion */
#include <stdio.h>
#include <stdlib.h>
int recurse(int x) {
int a[1<<15]; /* 4 * 2^15 = 64 KiB */
printf("x = %d. a at %p\n", x, a);
a[0] = (1<<14)-1;
a[a[0]] = x-1;
if (a[a[0]] == 0)
return -1;
return recurse(a[a[0]]) - 1;
}
int main(int argc, char *argv[]) {
int x = 100;
if (argc > 1)
x = atoi(argv[1]);
int v = recurse(x);
printf("x = %d. recurse(x) = %d\n", x, v);
return 0;
}
结论：这个程序是查看你所用的电脑中所分配的栈的大小，如我的运行结果可得
