PROGRAM 99

Object

Write a program that reads the name, roll number and marks of three subjects of four students and prints the total marks.

Algorithm

1. Declare a structure with the tag students.
2. Declare string name and integer variables rn, m1, m2 and m3 as the members of structure.
3. Declare an integer variable i.
4. Declare a variable s[4] of data type struct students.
5. Repeat FOR i = 0 to 3 by 1
   • Read structure members s[i].name, s[i].rn, s[i].m1, s[i].m2 and s[i].m3.
   • [End of FOR loop.]
6. Repeat FOR i = 0 to 3 by 1
   • Write structure members s[i].name, s[i].rn, s[i].m1, s[i].m2 and s[i].m3.
   • Write s[i].m1 + s[i].m2 + s[i].m3
   • [End of FOR loop.]
7. Exit.
