Struct inheritance in C

Question

Can a struct be inherited in C

User · Answer

Yes  struct is exactly like class except the default accessibility is public for struct  while it s private for class

User · Answer

Of course  In C    structs and classes are nearly identical  things like defaulting to public instead of private are among the small differences

Other than what Alex and Evan have already stated  I would like to add that a C   struct is not like a C struct   In C    a struct can have methods  inheritance  etc  just like a C   class

In C    a structure s inheritance is the same as a class except the following differences   When deriving a struct from a class struct  the default access-specifier for a base class struct is public  And when deriving a class  the default access specifier is private   For example  program 1 fails with a compilation error and program 2 works fine      Program 1  include  lt stdio h gt   class Base       public          int x      class Derived   Base         Is equivalent to class Derived   private Base     int main         Derived d      d x   20     Compiler error because inheritance is private     getchar        return 0        Program 2  include  lt stdio h gt   struct Base       public          int x      struct Derived   Base         Is equivalent to struct Derived   public Base     int main         Derived d      d x   20     Works fine because inheritance is public     getchar        return 0

Yes  The inheritance is public by default   Syntax  example    struct A      struct B   A      struct C   B

Yes  c   struct is very similar to c   class  except the fact that everything is publicly inherited    single   multilevel   hierarchical inheritance  but not hybrid and multiple inheritance   here is a code for demonstration  x000D   x000D   include lt bits stdc   h gt  using namespace std   struct parent       int data      parent     data 3                  default constructor     parent int x    data x             parameterized constructor    struct child   parent       int a   b      child    a 1    b 2                    default constructor     child int x  int y    a x    b y       parameterized constructor     child int x  int y int z               parameterized constructor               a   x          b   y          data   z            child const child  amp C                   copy constructor               a   C a          b   C b          data   C data           int main        child c1            c2 10   20            c3 10   20  30            c4 c3        auto print      const child  amp c    cout lt  lt c a lt  lt   t  lt  lt c b lt  lt   t  lt  lt c data lt  lt endl          print c1       print c2       print c3       print c4     OUTPUT  1       2       3 10      20      3 10      20      30 10      20      30 x000D   x000D   x000D
