Advanced Programming Techniques in D

Solution: Lets Play Cards

Explore how to define and use structs for card values and suits in D programming. Understand contract programming for error prevention and implement functions to build and shuffle a deck of cards, enhancing your struct and algorithm skills.

We'll cover the following...

Problem 1: Solution

D
struct Card {
    dchar suit;
    dchar value;
}
void main () {
}

Solution explanation

  • Lines 2 and 3:

Since we have to store the value and suit of the card, one of the simplest designs is to use two dchar members.

Problem 2: Solution

D
import std.stdio;
struct Card {
    dchar suit;
    dchar value;
    
    this(dchar s, dchar v) { // constructor
        suit = s;
        value = v;
    }
}
void printCard(Card card) {
    write(card.suit, card.value); 
}
void main() {
    auto card =  Card('♠','4');
    printCard(card);
}
