Basic Lines of Code in C#

• Types
  • int, long, double
• Variables
  • int n = 42;
  • var n = 42;
  • const int n = 42;
  • var words = new List<string>();
  • var M = new Matrix<double>(1000, 2000, 0.0);
  • var contactInfoForID = new Dictionary<string, ContactInfo>();
• Functions
  • static int multiply(int a, int b) { return a * b; }
  • static void print(ContactInfo a) { ... }
  • static string concat(string a, string b) { return ...; }
• Loops
  • for (int i = 1; i <= 10; ++i) { ... }
  • for (var i = 0; i < words.Count; ++i) { ... }
  • foreach (var i in new[] { 5, 7, 11, 13 }) { ... }
  • foreach (var word in words) { ... }

Note
In C# int and 42 are 32 bits wide, not 64 bits.
