C struct member size
WebEffect on struct size and padding The sizeof operator on such a struct gives the size of the structure as if the flexible array member were empty. This may include padding added to accommodate the flexible member; the compiler is also free to re-use such padding as part of the array itself.

WebAug 4, 2024 · It is known that the size of an empty class is not zero. Generally, it is 1 byte. The C++ Structures also follow the same principle as the C++ Classes follow, i.e. that structures in c++ will also not be of zero bytes. The minimum size must be one byte. Creating an empty structure in C/C++ is a syntactic constraint violation. Webstruct name_of_structure { // Multiple variables of different data types } The syntax of structure in C++ is very easy to understand and use.
