Hi Pupil Here's Your Answer :::




➡➡➡➡➡➡➡➡➡➡➡➡➡




An operating system is a system software, that after being initially loaded into the computer by a good program, manages all the other programs in a computer.

The application programs make use of the operating system by making request for services through a different Application Program Interface (API). In addition, users can interact directly with operating systems through a user interface such as command language or Graphical User Interface(GUI).


Functions Performed by the OS :


♤ The operating system acts as an interface between the computer hardware and the user.

♤ It manages computer's memory.

♤ It handles interrupts.

♤ It schedules the jobs.

♤ It manages Input/Output devices.


All major computer platforms (hardware and software) required and sometimes include an Operating System. Linux, Windows, Mac, VMS, OS/400 X, and z/OS are examples of operating systems.

Stolb23 [73]

Answer:

#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;

}
