Most of D's basic data types will be familiar to C-family programmers. In this section, we're first going to look at what the basic data types are. Then we'll discuss a couple of features that are related not only to the basic types, but to all types.
First up, D includes the special type
void to mean no type. There is no such thing as a variable of type
void. As in C,
void is used to indicate that a function does not return a value.
void pointers can be declared to represent pointers to any type.
Instances of the
bool type are guaranteed to be eight bits in size and can hold one of two possible values:
