Similar to the previous example, once we have the array pointer, we can access the vector’s elements as if they were in a traditional array. The provided loop iterates through the elements, printing them to the console. It’s important to note that while using the & operator to obtain ...

set和multiset会根据特定的排序准则,自动将元素进行排序。不同的是后者允许元素重复而前者不允许。 需要包含头文件: #include <set> set和multiset都是定义在std空间里的类模板: [cpp]view plain copy print? ...
