• Types
  • int, long, double
• Variables
  • int n = 42;
  • auto n = 42;
  • immutable int n = 42;
  • string[] words;
  • Matrix!double mat;
  • ContactInfo[string] contactInfoForID;
• Functions
  • int multiply(int a, int b) { return a * b; }
  • void print(ContactInfo a) { ... }
  • string concat(string a, string b) { return ...; }
• Loops
  • foreach (i; 1..11) { ... }
  • foreach (i; 0..words.length) { ... }
  • foreach (i; [5, 7, 11, 13]) { ... }
  • foreach (word; words) { ... }

In D int and 42 are 32 bits wide, not 64 bits.
