               scanf ("%d", &subject_5);

               //Calculate the sum and percentage.
               sum = subject_1 + subject_2 + subject_3 + subject_4 + subject_5;
               percentage = sum / 5.0;

               //Output the result.
               printf ("Total marks: %d\n", sum);
               printf ("Percentage: %.2f %", percentage);
