Program which read device data from a text file and show each extension’s dues

Posted By: Easy Tutor     Category: C++ Programming     Views: 3406

Write a program which read device data from a text file and show each extension’s dues.

Administration of GCU has decided to cut charges from its employee’s salaries. The VC of GCU orders a Software House to make software which should keep records of phone calls. And in the end of every month employees will receive their telephone bill at the rate of Rs.5 after every 5 minute call. The Software House bought a device to attach with the main telephone exchange. The device keeps record of incoming and outgoing calls for every extension. There are only 10 extensions in GCU from 0 to 9. 0 is extension of receptionist. Device saves data in following format;

Source Destination-1 Destination-2 Minutes
5666373, 0, 2, 7
6775775, 4, -, 10
3, 0, 7645303,2
4, 2, -,-
8, 6475774, -, 3

Make such a program which read this device data from a text file and show each extension’s dues e.g.

1 200
2 120
3 0
4 320
5 330
6 203
7 245
8 900
9 302

Note: Input will end with a line containing 0.

         cout<<"Press any key to exit."<<endl;

         getch( );
         exit(EXIT_FAILURE);
      }

       char Data[100]={NULL};

       char *Ptr=NULL;

       int source=0;
       int minutes=0;
       int bill[9]={0};

       File.getline(Data,80);

       do
      {
         source=-1;
         minutes=0;

         Ptr=NULL;
         Ptr=strtok(Data," ");

         if(atoi(Ptr)>0 && atoi(Ptr)<=9)
        source=(atoi(Ptr)-1);

         Ptr=NULL;
         Ptr=strtok(NULL," ");

         Ptr=NULL;
         Ptr=strtok(NULL," ");

         Ptr=NULL;
         Ptr=strtok(NULL,"\n");

         minutes=atoi(Ptr);

         if(source!=-1)
        {
           int calls=(minutes/5);

           if((minutes%5))
              calls++;

           bill[source]+=(calls*5);
        }

         strset(Data,NULL);
         File.getline(Data,80);
      }
       while(strcmpi(Data,"0")!=0);

       for(int count=0;count<9;count++)
      cout<<bill[count]<<endl;

       File.close( );

       getch( );
       return 0;
    }
