Abstract
The cardinalities of Cand E∞ are discussed based on the product sets theory of countable cardinality,whose cardinality still is ■.It is testified that the countable condition can′t be ■ because the cardinality of all the real function in bigger than ■.

The cardinalities of Cand E∞ are discussed based on the product sets theory of countable cardinality,whose cardinality still is ■.It is testified that the countable condition can′t be ■ because the cardinality of all the real function in bigger than ■.
