Program 11 Design a class “Selection_Sort” that inputs an array from the user and sorts it in ascending
order using the selection sort technique. A class is declared to give the details of the
constructor and member methods.

Data Members
int ar[] : Integer array to store array members
int n : To store the length of the array
Member Methods
Selection_Sort() : Constructor to initialise n to 0
void readlist() : To accept the value of n and array elements from the
user
int Index_Of_Min(int startindex) : To return the index position of the smallest value
void sort() : To sort the array in ascending order using selection
sort technique
void display() : To display the sorted array
Write the main method to call the methods and run the program.
