WebThe way to value-initialize a named variable before C++11 was T object = T();, which value-initializes a temporary and then copy-initializes the object: most compilers optimize out the copy in this case. References cannot be value-initialized. As described in functional cast, the syntax T() (1) is prohibited for arrays, while T{} (5) is allowed.
