Uninitialized

  The term "uninitialized" refers to any value is not initialized and therefore in an unusable state. If a value is uninitialized, the only valid operations on it are writes. The only way for an uninitialized value to stop being uninitialized is for it to undergo initialization. This does not include assignment even if the operator delete of the type of the value does not contain any read operations.

Examples:

• variables defined an initializer value
• value that undergoes operator delete
• value that undergoes operator destructive move
• value that undergoes operator forward
• element of an array after the array undergoes initialization
