WebJun 17, 2024 · A structure is a data type in C/C++ that allows a group of related variables to be treated as a single unit instead of separate entities. A structure may contain elements of different data types – int, char, float, double, etc. It may also contain an array as its member. Such an array is called an array within a structure. WebIt is because the sizeof () operator returns the size of a type in bytes. You learned from the Data Types chapter that an int type is usually 4 bytes, so from the example above, 4 x 5 (4 bytes x 5 elements) = 20 bytes. To find out how many elements an array has, you have to divide the size of the array by the size of the data type it contains: the st albans messenger obituaries
