From this: n1570 6.7.9 Initialization Semantics 8 An initializer specifies the initial value stored in an object. I would construe that the entire contents of an array, is the value of an array. The result of an implicit conversion of an expression of array type to a pointer, does not depend on the value of the array, but only depends on the address of the array. C does not have an operator which can assign the value of an array to another array and C does not have an operator which can compare the value of an array to another array. -- pete
