Syntax
Get familiarized with the pointer syntax in D.
The pointer syntax of D is almost the same as in C. Although this can be seen as an advantage, the peculiarities of C’s pointer syntax are also inherited by D For example, the different meanings of the *
character may be confusing.
With the exception of void pointers, every pointer is associated with a certain type and can point at only variables of that specific type. For example, an int
pointer can only point at variables of type int
.
The pointer definition syntax consists of the associated type and a *
character:
type_to_point_at * name_of_the_pointer_variable;
Accordingly, a pointer variable that points at int
variables is defined like this:
int * myPointer;
The *
character in this syntax may be pronounced as “pointer.” So, the type of myPointer
above is an “int pointer.” The spaces before and after the *
character are optional. The following syntaxes are common as well:
int* myPointer;
int *myPointer;
When it is specifically a pointer type that is being mentioned as in “int pointer”, it is common to write the type without any spaces as in int*
.
