Cannot capture the non-constant value
Webis a reference that has been initialized with a constant expression . A lambda expression can read the value of a variable without capturing it if the variable. has const non-volatile integral or enumeration type and has been initialized with a constant expression, or. is constexpr and has no mutable members. WebIn mathematics, the word constant conveys multiple meanings. As an adjective, it refers to non-variance (i.e. unchanging with respect to some other value); as a noun, it has two different meanings: .
