私はC++で単純な継承プログラムを書いていますが、多くのエラーがあります

Question

何が間違っているのか分かりません。私は相続が新しい。私が得たすべてのエラーを含む：

21 7 D:\My C++ programs\inheritance.cpp [Error] redefinition of 'class Sharad'

    { 
Sourabh s1; 
    s1.getinfo(); 
    s1.showinfo(); 
    getch(); 
    return 0; 
} 

Answer 1

class Sharad : public Sourabh 

これは、周りの間違った方法です。 SourabhSharadから継承する新しいクラスです：

class Sourabh : public Sharad
