Advanced Programming Techniques in D

Member Access and Member Functions

Explore how to access members in D classes and define member functions. Understand the differences between structs and classes, focusing on member function overriding and operator overloading for advanced D programming.

We'll cover the following...

Member access

Like structs, the members are accessed by the dot operator:

D
import std.stdio;
class ChessPiece {
    dchar shape;
    
    this(dchar shape) {
      this.shape = shape; 
    }
}
void main() {
    auto king = new ChessPiece('♔');   
    writeln(king.shape);
}

Although the syntax makes it look as if a member of the variable is being accessed, it is actually a member of the object. Class variables do not have members, the class objects do. The king variable does not have a shape member, the anonymous object ...
