Question

Quizplus · Accepted Answer

The sizeof() operator in C++ returns the size (in bytes) of the specified data type. It can also be used to find the size of an array or a variable. Therefore, option B is the best choice. The sizeof() operator is used to determine the number of bytes used to store values for any datatype named in the operator's parentheses. The size() function exists in many libraries in C++, but it is not a built-in operator like sizeof(). The length() function is used for strings and arrays, and the lengthof() is not a valid operator or function in C++.
