That's C.  6.5.3.4 (2) reads:

2 The sizeof operator yields the size (in bytes) of its operand, which may be
an expression or the parenthesized name of a type. The size is determined from
the type of the operand. The result is an integer. If the type of the operand
is a variable length array type, the operand is evaluated; otherwise, the
operand is not evaluated and the result is an integer constant.
