WebNov 8, 2024 · An array is a sequence of objects of the same type that occupy a contiguous area of memory. Traditional C-style arrays are the source of many bugs, but are still common, especially in older code bases. In modern C++, we strongly recommend using std::vector or std::array instead of C-style arrays described in this section. 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:
