Почему литералы символов C являются целыми, а не символами? ⇐ C++

[Anonymous]

В C++

Код: Выделить всё

sizeof('a') == sizeof(char) == 1

. This makes intuitive sense, since

Код: Выделить всё

'a'

is a character literal, and

Код: Выделить всё

sizeof(char) == 1

as defined by the standard.

In C however,

Код: Выделить всё

sizeof('a') == sizeof(int)

. That is, it appears that C character literals are actually integers. Does anyone know why? I can find plenty of mentions of this C quirk but no explanation for why it exists.
