Journal Program 5

 /*

Def: WAP to build a class MyArray having integer array as

a data member and following member fuctions:

(a)getData() : To get n values for integer array

(b)sort_asc() : To sort an array in ascending order

(c)sort_desc() : To sort an array in descending order

(d)putData() : To print all values

Write a menu driven program for sorting either ascending

and descending order and also for exit from a program.
