这两个方法是与std::vector::begin和std::vector::end相对应的,从字面就能看出来,多了一个’c’,顾名思义就是const的意思。 所以: std::vector::cbegin:Returns a const_iterator pointing to the first element in the container. std::vector::cend:Returns a const_iterator pointing to the past-the-...

StringVector names = {0}; string_vector_add(&names, "John"); string_vector_add(&names, "Alie"); string_vector_add(&names, "Josh"); Here, because you haven't explicitly initialized the vector with string_vector_init(), it's automatically initialized to hold, by default, 10 strings....
capacity() - 类 javax.swing.DefaultListModel 中的方法 返回此列表的当前容量。 capacityIncrement - 类 java.util.Vector 中的变量 向量的大小大于其容量时,容量自动增加的量。 capacityIncrement - 类 javax.management.monitor.Monitor 中的静态变量 监视器数组的大小大于其容量时,容量自动递增的量。 cap...
