C + + defines a standard transformation between a set of built-in type objects that are implicitly applied to the object by the compiler, if necessary.Implicit type conversions occur in the following typical scenarios.1. In a mixed-type arithmetic

Recently learning C + +, the concept of namespace is rather curious, but the online information is very fragmented, and do not want to go through the thick C + + Primer Plus. So he experimented.1. and are not the same, the former has no suffix, in

The function of the keyword sizeof is to return the number of bytes of memory consumed by the object or type, and the return value is size_t.Number of bytes consumed by the base data type: (32-bit system)Char 1 bytesBOOL 1 bytesShort 2 bytesint 4
