This function has two purposes: one is two iterate backwards through a UTF-8 encoded string. Note that it is usually a better idea to iterate forward instead, sinceutf8::nextis faster. The second purpose is to find a beginning of a UTF-8 sequence if we have a random position within a...
当处理输入数据时,通常可以很容易地向 vector 追加数据,然后再调用标准库的 sort 函数来重排容器中的元素,从而避免在中间位置添加元素。 如果必须在中间位置插入元素,考虑在输入阶段使用 list, 一旦输入完成,将 list 中的内容拷贝到一个 vector 中。 容器类型别名说明 iterator 此容器的迭代器类型 const_iterateor ...
Even today, people still write classes in this style and get into trouble: “I pushed a person into a vector and now I get crazy memory errors!” Remember that by default, copying an object means copying its members, but copying the name member merely copies a pointer, not the character...

// Find the element in the vector. <-- 差: 这太明显了! auto iter = std::find(v.begin(), v.end(), element); if (iter != v.end()) { Process(element); } 和这样的注释: // Process "element" unless it was already processed. auto iter = std::find(v.begin(), v.end(),...

but to demonstrate how to do this with PHP-CPP we are going to build it with C++. Just like all the other functions that you've seen in the earlier examples, such a C++ function function receives a Php::Parameters object as its parameter, which is a std::vector of Php::Value objects...
