                  问题描述

                  通常我们可以为 C++ 结构定义一个变量,如

                  Usually we can define a variable for a C++ struct, as in

                  struct foo {
                    int bar;
                  };
                  

                  我们也可以为结构定义函数吗?我们将如何使用这些功能?

                  Can we also define functions for a struct? How would we use those functions?

                  推荐答案

                  是的,structclass 相同,除了默认的访问级别(member-wise和继承方面).(以及 class 与模板一起使用时的额外含义)

                  Yes, a struct is identical to a class except for the default access level (member-wise and inheritance-wise). (and the extra meaning class carries when used with a template)

                  一个类支持的每一个功能都因此得到一个结构的支持.您使用的方法与在类中使用方法相同.

                  Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.

                  struct foo {
                    int bar;
                    foo() : bar(3) {}   //look, a constructor
                    int getBar() 
                    { 
                      return bar; 
                    }
                  };
                  
                  foo f;
                  int y = f.getBar(); // y is 3
