Operators

C# supports the usual arithmetic (+ - * / % ++ --), comparison (== != > < >= <=), and logical (&& || !) operators — and, for string, == compares content, not references, unlike Java.

int a = 7, b = 2;
Console.WriteLine(a / b);            // 3 — integer division truncates
Console.WriteLine((double) a / b);   // 3.5 — cast one side first

string x = "hi";
string y = "hi";
Console.WriteLine(x == y); // true — compares content, as expected

Common mistakes

• Forgetting integer division truncates: 7 / 2 is 3, not 3.5.
