type promotion and type conversion

[vencent]

Hi,does anyone know the difference between Type promotion and Type conversion? I am really confused. Thanks a lot.

Type conversion I think is a cast; any situation where one type is cast to another. Static cast, C-style cast, etc.

Type promotion, I believe, is a special type of that situation where an integer is cast to a larger integer type ("promoted").

promotion is only for integer type, that's the point. Thanks a lot.
