I use a lot standard c++ gcd function (__gcd(x, y)). But today, I learnt that on some compiler __gcd(0, 0) gives exception. (Maybe because 0 is divisible by any number?! ) Note for myself and everybody:While using __gcd we must carefully handle (0, 0) case or write own ...
5. 将上面源代码转化成cpp代码: static void _I_MyPerson_run(MyPerson * self, SEL _cmd) { { id _rethrow = 0; id _sync_obj = (id)self; objc_sync_enter(_sync_obj); try { struct _SYNC_EXIT { _SYNC_EXIT(id arg) : sync_exit(arg) {} ~_SYNC_EXIT() {objc_sync_exit(sync_e...
例如：我们重新实现对象的event()方法，并让它调用函数器。这需要在函数被发送到的每个线程中有一个显...

* Static function to create a new ObjectLibrary at runtime, with various options set * There is now a better version of this functionality in AssetManager, if you are creating many game-specific libraries you should switch to using AssetManager instead ...
函数gcd没有定义。在main函数前加上以下一段，试第N+1次，保证成功。成功后别忘了采纳哟……int gcd(int a,int b){ int r;if(b==0 || a==0)return 0;while(r=a%b)a=b,b=r;return b;}
