使用insert函数逐个插入元素: std::map<Key, Value> myMap; myMap.insert(std::make_pair(key1, value1)); myMap.insert(std::make_pair(key2, value2)); ... 这将创建一个空的std::map对象,并使用insert函数逐个插入键值对。 std::map的优势在于它提供了快速的查找和插入操作,其内部实现使用红黑树...
The pair iterator is used to access elements of nullable columns as a pair containing an element's value and validity. cudf::detail::make_pair_iterator can be used to create a pair iterator from a column_device_view or a cudf::scalar. make_pair_iterator is not available for mutable_...
第一行是cmake的最低版本要求 第二行指定了项目名称,可以是别名 第三行是指定了编译版本,这里是C++ 11 第四行是加入执行器,需要两个参数,第一个参数必须是正确的项目名称,第二个参数是main函数所在位置,也就是执行器入口。 都设置好以后,开始执行,打出正确日志: /home/liuwenbin/work/CLionProjects/github....
