basic_string的元素是连续存储的,即对于basic_strings,对[0,s.size())中的任意n有&*(s.begin()+n)==&*s.begin()+n,或等价地,指向s[0]的指针能传递给期待指向CharT的空终止(C++11 起)数组首元素指针的函数。 std::basic_string满足知分配器容器(AllocatorAwareContainer)(但不使用定制的construct...

If the array holding the first string isn't large enough to hold both strings, strcat will overflow the boundaries of the array. char string1[100] = "Hello "; // string1 has enough capacity for strcat char string2[] = "World!"; strcat(string1, string2); cout << string1 << endl...

For the scenario above, even if the first client actually crashes, requests sent by 2 clients can be re-ordered in the network and hit the external resource in reverse order.There is a simple solution for this problem. Lock holders are ordered by a monotonic fencing token, which increments ...
