Create a class str that subclasses str. add a method to the subclass that checks if the string does not start with a given string. call that method notstartswith

#include <iostream>

using namespace std;

class Str{  ///baseclass

   public :

   string super_str;

   string getStr()

   {

       return super_str;

   }

   void setStr(string String)

   {

       super_str=String;

   }

};

class str : public Str{   //inheriting Str publicly

   public :

       string sub_str;

       string getstr()

       {

           return sub_str;

       }

       void setstr(string String)

       {

           sub_str=String;

       }

       bool notstartswith()

       {

           int n=sub_str.length();   //to find length of substr

           bool flag=false;

           for(int i=0;i<n;i++)     //Loop to check beginning of Str

           {

               if(super_str[i]!=sub_str[i])

               {

                   flag=true;

                   break;

               }

           }

           return flag;

       }

};

int main()

{

   str s;    //object of subclass

   s.setStr("Helloworld");  

   s.setstr("Hey");

   if(s.notstartswith()==1)     //checking if str is substring of Str

       cout<<"Str does not start with str";

   else

       cout<<"Str starts with str";

   return 0;

}

OUTPUT :

Str does not start with str

Explanation:

Above program is implemented the way as mentioned. for loop is being used to check the beginning of the str starts with substring or not.

i'm pretty sure data is stored in a form
