Write a program to calculate the subject wise and student
wise totals and store them as a part of the structure.

array of structures of type 'marks' . . . .

struct marks totals; // One more
structure variable 'totals' to store totals

{45,67,81,0} à Values for different members of student[0] which is of type
'marks'
{75,53,69,0}, à Values for Student[1]
{ 57,36,71,0} à Values for Student[3]
student[i].total à Assigning
value to 'total' member of student[i]
student[i].sub1 à Value for
'sub1' member of student[i]

OUTPUT:
Student total
Student[1] 93
Student[2] 97
Student[3] 64
Subject total
Subject1 77
Subject2 56
Subject3 71
Grand total = 458
