CPP C++ C++ C++ vector::empty() and vector::size() in C++ STL Vectors 与动态数组相同,能够在插入或删除元素时自动调整大小,其存储由容器自动处理. vector::empty() empty()函数用于检查向量容器是否为空。语法: vectorname.empty() Parameters : No parameters

C++ STL array::empty() function with Example: Here, we are going to learn about a library function empty() of array class, which is used to check whether an array is empty or not.
Thevector()function in R is used to create a vector of the specified length and type specified bylengthandmode. Themodeby default is logical but can be changed to numeric, character, or even to list or some expression. An example to create an empty Vector is shown below: ...
