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: Web1 day ago · In the book "The C++ Programming Language, 4th Edition" by Stroustrup, it's mentioned that the size of wchar_t is implementation-defined and large enough to hold the largest character set
