Answer 1

把那#include<stdbool.h>
改为以下三行.
#define bool int
#define false 0
#define true 1
换符合C99标准的编译器吧,凡是1999年以后出的编译器都行,如vs,gcc.

#ifndef __bool_true_false_are_defined

/* program is allowed to contain its own definitions, so ... */
#undef bool
#undef true
#undef false

Answer 3

bool改int
#include <stdbool.h>这一行不要
