PROGRAM 100

Object

Write a program that demonstrates the process of arrays of structures.

Algorithm

1. Declare an integer variable i.
2. Declare a structure with the tag entry.
3. Declare strings fname that contains 20 elements, lname that contains 20 elements and phone that contains 15 elements as the members of structure.
4. Declare a variable list[4] of data type struct entry.
5. Repeat FOR i = 0 to 3 by 1
   • Read structure members list[i].fname, list[i].lname and list[i].phone.
   • [End of FOR loop.]
6. Repeat FOR i = 0 to 3 by 1
   • Write structure members list[i].fname, list[i].lname and list[i].phone.
   • [End of FOR loop.]
7. Exit.
