A function call is always an rvalue. True or false?
AnswerClick to flip back
A
False
💡 Explanation:
A function call is not always an rvalue in C/C++. Whether it's an rvalue depends on the return type - if a function returns by value, the call is an rvalue, but if it returns a reference, it can be an lvalue. For example, a function returning int& can be used as an lvalue.
