CopyConstructible

Specifies that an instance of the type can be copy-constructed from an lvalue expression.

Requirements

The type T satisfies CopyConstructible if.

The type T satisfies MoveConstructible, and

Given.

v, an lvalue expression of type T or const T or an rvalue expression of type const T
u, an arbitrary identifier

The following expressions must be valid and have their specified effects.

Expression	Post-conditions
`T u = v;`	The value of `u` is equivalent to the value of `v`. The value of `v` is unchanged.
`T(v)`	The value of `T(v)` is equivalent to the value of `v`. The value of `v` is unchanged.

The expression v.~T() also must be valid, and, for lvalue v, the expression &v must have the type T* or const T* and must evaluate to the address of v.

(until C++11)

Notes

Until C++11, classes that overloaded operator& were not CopyConstructible and thus weren't usable in the standard library containers. As of C++11, the standard library uses std::addressof whenever the address of an object is needed.
