5. User-defined types

• Keywords struct and class

  
      struct Point { int x; int y; };
      -or-
      class Point {
      public:
          int x; 
          int y;
      };
  
      Point p1; // Note: struct keyword not needed
      p1.x = 9;
      p1.x = 2;
  
  
  

• C supports structs. In C++ structs and classes can also have functions.
