Posted By: Easy Tutor     Category: C++ Programming     Views: 20083

A C++ Program that reads the marks obtained of ten students out of 100. It also computes the average , lowest and highest marks.Then shows the difference of marks of every student from the average marks.

Code for Program that reads 10 students marks and displays average, lowest and highest marks in C++ Programming


 #include<iostream.h>
 #include<conio.h>

 float average_marks(float []);
 float highest_marks(float []);
 float lowest_marks(float []);

 main()
    {
       clrscr();

       float marks[10]={0};

       cout<<"\n Enter the marks of the ten students : "<<endl;
       cout<<"\n\t Student No.       Marks Obtained"<<endl;

       for(int count_1=0;count_1<10;count_1++)
      {
         cout<<"\t\t"<<count_1+1<<"\t\t";
         cin>>marks[count_1];
      }

       getch();
       clrscr();

       cout<<"\n ********************  Result Sheet  ****************"<<endl;

       cout<<"\n Total Marks = 100"<<endl;
       cout<<" Average Marks  = "<<average_marks(marks)<<endl;
       cout<<" Highest Marks obtained = "<<highest_marks(marks)<<endl;
       cout<<" Lowest Marks obtained = "<<lowest_marks(marks)<<endl;

       cout<<"\n   Student No.    Marks Obtained     Diff. from Average Marks      Status"<<endl;

int y=10;
       for(int count_2=0;count_2<10;count_2++)
      {
         cout<<"\t"<<count_2+1<<"\t\t"<<marks[count_2];
         gotoxy(42,y);
         cout<<marks[count_2]-average_marks(marks)<<"\t\t   "<<
                 ((marks[count_2]>=50)?"Pass":"Fail")<<endl;
         y++;
      }

       getch();
       return 0;
    }

        highest=marks[count];
      }

       return highest;
    }
