The underlying representation is a 16-bit number, so it can be converted (through explicit cast) to and from an integer. The expression (char)0 casts the integer value 0 to the corresponding unicode character '\0', which is the default value. Share.

The effects of zero-initialization are: If T is a scalar type, the object is initialized to the value obtained by explicitly converting the integer literal 0 (zero) to T. If T is a non-union class type:
